The INA129UA is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

V+: Positive power supply pin.
V-: Negative power supply pin.
REF: Reference voltage pin.
RG: Gain setting resistor pin.
IN-: Inverting input pin.
IN+: Non-inverting input pin.
OUT: Output pin.
VS-: Supply voltage pin for internal circuitry.

What are the Pros and Cons of INA129UA?

Pros:

Precision Amplification: Provides accurate amplification of small differential signals.
