FEATURE DESCRIPTION
Overview
Bandwidth
The features of the SGM8198 are high voltage,
precision measurement, precision resistors trimmed for
meeting the absolute tolerance and the ability of low
noise. Also, the SGM8198 can be powered by a single
power supply and the input voltage level can exceed the
supply voltage level. In addition, the SGM8198 can
measure the small sense voltage at a higher common
mode voltage level. The Functional Block Diagram
illustrates the internal structure of the SGM8198.
The value of the load resistor (RL) has a significant
effect on the measurement bandwidth. A narrower
measurement bandwidth due to high gain is generated
by the high RL values. Therefore, the widest possible
bandwidth can be obtained when the capacitive load on
the output is kept to a minimum. For details of
bandwidth reduction due to capacitive load, please
refer to Typical Performance Characteristics.
As shown in Figure 5, adding a capacitor to the output
can achieve the bandwidth limitation (filtering). And this
operation will not cause system instability.
Range of Output Voltage
The load resistor RL is used to convert the output
current into voltage accurately. The maximum output
swing of the SGM8198 is limited by the supply voltage,
the common mode voltage, and the sense voltage.
Device Functional Modes
The device specifications are shown in Electrical
Characteristics. For proper operation, the following
recommendations should be met for operating
SGM8198:
The device should be powered within the voltage
range from 2.7V to 36V.
The input common mode voltage range is from 2.7V
to 36V.

APPLICATION INFORMATION
gm, is equal to 1000μA/V. The relationship between IS
and VOUT is shown in Equation 2:
Operation
The basic structure of SGM8198 is shown in Figure 3.
The measured load current is drawn from the supply
voltage of the SGM8198. The internal amplifier forces
the current to flow into the drain of the MOSFET (M1).
The load resistor RL is used to convert the output
current into output voltage.
(2)
VOUT = IS × RS × (1000μA/V) × RL
For accuracy measurement, the maximum sense
voltage is limited to 0.5V, which can produce 500μA
output current for the load. The maximum sense
voltage that will not cause damage is 2V. For normal
operation, the voltage applied to pin 3 should be
greater than pin 4. If the applied voltage at pin 3 is
smaller than that of pin 4, the SGM8198 will not be
damaged and the output current is equal to 0μA.

TYPICAL APPLICATIONS
The SGM8198 is available for most applications. The
examples are shown from Figure 7 to Figure 10.
enhancing the accuracy of the measurement, the input
impedance of the external circuitry which is connected to
the output of the SGM8198 should be much larger than
100kΩ.
Buffering Output to Drive an ADC
The Analog-to-Digital converters (ADC) may have the
input impedance that will affect the gain of the
SGM8198 since it can be paralleled with RL.
Alternatively, the buffer should be placed between the
ADC and SGM8198. The output impedance of the
SGM8198 is significant larger as it is a current source.
The load resistor RL is used to convert the load current
to the specific desired voltage. The ratio of the value of
the load resistor to the internal resistor RG determines
the voltage gain of the device.

Design Requirements
Digitize the output of the SGM8198 device using a
1MSPS Analog-to-Digital converter (ADC).
For most of the applications which need to digitize the
output of the SGM8198, an ADC is required for
completing this requirement. However, for the analog
input stage of ADC, there is a dynamic input impedance
which can be paralleled with RL and affect the voltage
gain of SGM8198. Also, the accuracy of the SGM8198
cannot be guaranteed for this situation. To avoid any
external impedance which is paralleled with RL, a buffer
should be placed between the output of SGM8198 and
the analog input of ADC. The SGM8955 is a good
choice for the buffer.
Detailed Design Procedure
Selecting RS and RL
The choice of RS is related to the accuracy of the small
input signal and the maximum allowable voltage drop
across RS of the measured line. For measuring low
current, a larger RS can be taken into account to
minimize the effect of the offset voltage and then
enhance the accuracy. Lower RS can reduce the
voltage loss dramatically in supply line. The best
performance of the SGM8198 for the sense voltage
should be in the range of 50mV to 100mV, and the
maximum allowable sense voltage for accurate
measurement is 500mV, which can handle most of the
applications.
Figure 4 shows how to digitize the output of SGM8198
with an addition buffer. Between the output of the buffer
and the input of the ADC, an RC filter can be added.
The capacitor should provide any instantaneous
current demand for the input stage of ADC. The resistor
should be considered to isolate the buffer output from
the load capacitor to enhance the stability. The values
of the resistor and the capacitor for the filter should be
varied for different selections of buffer and ADC.
The desired output voltage for the SGM8198 is
determined by the value of RL. Because of the high
impedance structure of the SGM8198, the device
allows the maximum resistance of RL to be 100kΩ. For

Output Filter
Offsetting the Output Voltage
If the customers need to offset the output voltage away
from GND when there is no load current flowing
through RS for single power supply, SGMICRO
recommends the following two methods, as shown in
Figure 7. The voltage divider method is shown in the
left hand side. This method can locate the level of
output voltage at the center of VR when there is no
current flowing through RS. With this method, the gain
of the SGM8198 is determined by the parallel
combination of R1 and R2 and the offset level is
determined by the voltage divider of them. If the
customers need a fixed offset level which is not related
with its supply voltage, a constant current source can
be taken into account. With this method, the gain is
determined by RL and the offset voltage is determined
by the multiplication product of constant current which
is provided by the current source and the load resistor
RL.

cutoff frequency with the equation shown in Figure 5.

and the GND. In this application, the 20V/V gain is
generated by the 20kΩ resistor. The two 10kΩ resistors
provide a voltage input for the SGM8740. In this
example, there is only one SGM8198 can operate at a
time as the two SGM8198 measures positive and
negative current respectively, so two diodes should be
placed at the output of them to prevent the current
flowing into the output.
Bipolar Current Measurement
The following circuitry can be taken into account for the
applications which needs to measure positive and
negative current flowing through the RSH. The two
inputs of each SGM8198 are connected at the two
sides of RSH together. The comparator can indicate if
the current flowing is positive or negative. The

resistor which is located between the labeled output

the measured current flowing, one of the outputs of SGM8198 must have a corresponding value and the other one is

The two input pins can measure the differential voltage accurately though their input common mode voltage which is
higher than the supply voltage of the SGM8198. For instance, the two input pins can measure the current from a
36V system with 5V power supply voltage. A 0.1μF bypass capacitor should be placed as close as possible to the
supply pin. For noisy power supply applications, an additional capacitor will be required.

The recommendation of PCB layout for SGM8198 is
shown in Figure 11. The input pins of SGM8198 should
be placed closely to the measured load current to
minimize the resistance which is in series with the
shunt resistor RS. The output resistor RL is connected
between OUT and GND pins. For enhancing the
accuracy of the measurement, the operator should
measure the voltage at the RL directly. In some
The SGM8198 does not need any bypass capacitors
for its stability. However, for noisy power supply, the
capacitors are needed and should be placed as close
as possible to the power supply pin for rejecting any
noise from the power supply.
