ESD Susceptibility
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.

10μF
The SGMOP17C supports rail-to-rail output operation.
In single power supply application, for example, when
+VS = 36V, -VS = GND, 10kΩ load resistor is tied from
OUT pin to ground, the typical output swing range is
from 0.095V to 35.905V.

Driving Capacitive Loads
+
+
The SGMOP17C is unity-gain stable with heavy
capacitive load. If greater capacitive load must be
driven in application, the circuit in Figure 1 can be used.
In this circuit, the IR drop voltage generated by RISO is
compensated by feedback loop.

Grounding
_
In low speed application, one node grounding technique
is the simplest and most effective method to eliminate
the noise generated by grounding. In high speed
application, the general method to eliminate noise is to
use a complete ground plane technique, and the whole
ground plane will help distribute heat and reduce EMI
noise pickup.

Power Supply Decoupling and Layout
A clean and low noise power supply is very important in
amplifier circuit design, besides of input signal noise,
the power supply is one of important source of noise to
the amplifier through +VS and -VS pins. Power supply
bypassing is an effective method to clear up the noise
at power supply, and the low impedance path to ground
of decoupling capacitor will bypass the noise to GND.
In application, 10μF ceramic capacitor paralleled with
0.1μF or 0.01μF ceramic capacitor is used in Figure 2.
The ceramic capacitors should be placed as close as
possible to +VS and -VS power supply pins.
Reduce Input-to-Output Coupling
To reduce the input-to-output coupling, the input traces
must be placed as far away from the power supply or
output traces as possible. The sensitive trace must not
be placed in parallel with the noisy trace in same layer.
They must be placed perpendicularly in different layers
to reduce the crosstalk. These PCB layout techniques
will help to reduce unwanted positive feedback and
noise.

Active Low-Pass Filter
Typical Application Circuits
The circuit in Figure 5 is a design example of active
low-pass filter, the DC gain is equal to -R2/R1 and the
-3dB corner frequency is equal to 1/2πR2C. In this
design, the filter bandwidth must be less than the
bandwidth of the amplifier, the resistor values must be
selected as low as possible to reduce ringing or
oscillation generated by the parasitic parameters in
PCB layout.
Difference Amplifier
The circuit in Figure 3 is a design example of classical
difference amplifier. If R4/R3 = R2/R1, then VOUT = (VP -
VN) × R2/R1 + VREF
