GENERAL DESCRIPTION
The AD8210 is a single-supply difference amplifier ideal for
amplifying small differential voltages in the presence of large
common-mode voltages. The operating input common-mode
voltage range extends from −2 V to +65 V. The typical supply
voltage is 5 V.
The output offset can be adjusted from 0.05 V to 4.9 V with
a 5 V supply by using VREF1 pin and VREF2 pin. With the VREF
pin attached to the V+ pin, and the VREF2 pin attached to the
GND pin, the output is set at half scale. Attaching both VREF1
and VREF2 to GND causes the output to be unipolar, starting
near ground. Attaching both VREF1 and VREF2 to V+ causes the
output to be unipolar, starting near V+. Other offsets can be
obtained by applying an external voltage to VREF1 and VREF2.

The AD8210 is offered in a SOIC package. The operating
temperature range is −40°C to +125°C.
Excellent ac and dc performance over temperature keep errors
in the measurement loop to a minimum. Offset drift and gain
drift are guaranteed to a maximum of 8 μV/°C and 20 ppm/°C,
respectively.

AD8210
THEORY OF OPERATION
differential signal is nonzero, the current increases through one
of the resistors and decreases in the other. The current
difference is proportional to the size and polarity of the input
signal.
In typical applications, the AD8210 amplifies a small differential
input voltage generated by the load current flowing through a
shunt resistor. The AD8210 rejects high common-mode voltages
(up to 65 V) and provides a ground referenced buffered output
that interfaces with an analog-to-digital converter. Figure 26
shows a simplified schematic of the AD8210.
The differential currents through Q1 and Q2 are converted into
a differential voltage by R3 and R4. A2 is configured as an
instrumentation amplifier. The differential voltage is converted
into a single-ended output voltage by A2. The gain is internally
set with precision trimmed, thin film resistors to 20 V/V.
The AD8210 is comprised of two main blocks, a differential
amplifier and an instrumentation amplifier. A load current
flowing through the external shunt resistor produces a voltage
at the input terminals of the AD8210. The input terminals are
connected to the differential amplifier (A1) by Resistor R1 and
Resistor R2. A1 nulls the voltage appearing across its own input
terminals by adjusting the current through R1 and R2 with
Transistor Q1 and Transistor Q2. When the input signal to the
AD8210 is 0 V, the currents in R1 and R2 are equal. When the
The output reference voltage is easily adjusted by the VREF1 pin
and VREF2 pin. In a typical configuration, VREF1 is connected to
VCC while VREF2 is connected to GND. In this case, the output is
centered at VCC/2 when the input signal is 0 V.

MODES OF OPERATION
V+ Referenced Output
The AD8210 can be adjusted for unidirectional or bidirectional
operation.
This mode is set when both reference pins are tied to the
positive supply. It is typically used when the diagnostic scheme
requires detection of the amplifier and wiring before power is
applied to the load (see Figure 28 and Table 5).
UNIDIRECTIONAL OPERATION
Unidirectional operation allows the AD8210 to measure
currents through a resistive shunt in one direction. The basic
modes for unidirectional operation are ground referenced
output mode and V+ referenced output mode.
R
S
+IN
–IN
In unidirectional operation, the output can be set at the negative
rail (near ground) or at the positive rail (near V+) when the
differential input is 0 V. The output moves to the opposite rail
when a correct polarity differential input voltage is applied. In
this case, full scale is approximately 250 mV. The required
polarity of the differential input depends on the output voltage
setting. If the output is set at ground, then the polarity needs to
be positive to move the output up (see Table 5). If the output is
set at the positive rail, then the input polarity needs to be
negative to move the output down (see Table 6).

When using the AD8210 in this mode, both reference inputs

BIDIRECTIONAL OPERATION
Bidirectional operation allows the AD8210 to measure currents
through a resistive shunt in two directions. The output offset
can be set anywhere within the output range. Typically, it is set
at half scale for equal measurement range in both directions. In
some cases, however, it is set at a voltage other than half scale
when the bidirectional current is nonsymmetrical.

External Referenced Output
R
S
Tying both VREF pins together to an external reference produces
an output offset at the reference voltage when there is no
differential input (see Figure 29). When the input is negative
relative to the −IN pin, the output moves down from the
reference voltage. When the input is positive relative to the
−IN pin, the output increases.

By tying one reference pin to V+ and the other to the GND pin,
the output is set at mid supply when there is no differential
input (see Figure 31). This mode is beneficial because no
external reference is required to offset the output for
bidirectional current measurement. This creates a midscale
offset that is ratiometric to the supply, meaning that if the
supply increases or decreases, the output still remains at half
scale. For example, if the supply is 5.0 V, the output is at half
scale or 2.5 V. If the supply increases by 10% (to 5.5 V), the
output also increases by 10% (2.75 V).

Splitting an External Reference
In this case, an external reference is divided by two with
an accuracy of approximately 0.2% by connecting one
REF pin to ground and the other VREF pin to the reference

voltage (see Figure 30).

Note that Pin VREF1 and Pin VREF2 are tied to internal precision
resistors that connect to an internal offset node. There is no

For proper operation, the AD8210 output offset should not be
set with a resistor voltage divider. Any additional external
resistance could create a gain error. A low impedance voltage
source should be used to set the output offset of the AD8210.

INPUT FILTERING
In typical applications such as motor and solenoid current
sensing, filtering at the input of the AD8210 can be beneficial in
reducing differential noise, as well as transients and current
ripples flowing through the input shunt resistor. An input low-
pass filter can be implemented as shown in Figure 32.
Adding outside components such as RFILTER and CFILTER
introduces additional errors to the system. To minimize these
errors as much as possible, it is recommended that RFILTER be
10 Ω or lower. By adding the RFILTER in series with the 2 kꢀ
internal input resistors of the AD8210, a gain error is
introduced. This can be calculated using the following formula:

In this case, the PWM control switch is ground referenced. An
inductive load (solenoid) is tied to a power supply. A resistive
shunt is placed between the switch and the load (see Figure 33).
An advantage of placing the shunt on the high side is that the
entire current, including the recirculation current, can be meas-
ured because the shunt remains in the loop when the switch is
off. In addition, diagnostics can be enhanced because short circuits
to ground can be detected with the shunt on the high side.
Figure 34. High-Side Switch
Using a high-side switch connects the battery voltage to the
load when the switch is closed. This causes the common-mode
voltage to increase to the battery voltage. In this case, when the
switch is opened, the voltage reversal across the inductive load
causes the common-mode voltage to be held one diode drop
below ground by the clamp diode.

Another typical application for the AD8210 is as part of the
control loop in H-bridge motor control. In this case, the AD8210
is placed in the middle of the H-bridge (see Figure 35) so that it
can accurately measure current in both directions by using the
shunt available at the motor. This configuration is beneficial for
measuring the recirculation current to further enhance the
control loop diagnostics.

In this circuit configuration, when the switch is closed, the
common-mode voltage moves down to the negative rail. When
the switch is opened, the voltage reversal across the inductive
load causes the common-mode voltage to be held one diode
drop above the battery by the clamp diode.

Figure 35. Motor Control Application
This configuration minimizes the possibility of unexpected
solenoid activation and excessive corrosion (see Figure 34). In
this case, both the switch and the shunt are on the high side.
When the switch is off, the battery is removed from the load,
which prevents damage from potential short circuits to ground,
while still allowing the recirculation current to be measured and
diagnostics to be preformed. Removing the power supply from
the load for the majority of the time minimizes the corrosive
effects that could be caused by the differential voltage between
the load and ground.
The AD8210 measures current in both directions as the H-bridge
switches and the motor changes direction. The output of the
AD8210 is configured in an external reference bidirectional
mode; see the Modes of Operation section.
