INA2332AIPWR from Texas Instruments, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RGA passive Channel A external gain-set resistor node. Connect resistors R1 (to internal 10 kΩ tap) and R2 (to output) to set gain per G = 5 + 5(R2/R1); leave open for the internal G = 5 configuration.
2 VIN-A input Channel A inverting differential signal input. Diode-clamped to the supply rails; external signals must be current-limited to ≤10 mA if driven >0.5 V beyond the rails.
3 VIN+A input Channel A non-inverting differential signal input. High-impedance CMOS input (10^13 Ω
4 V- power_in Negative supply / ground for both channels. Tie to GND for single-supply operation or to the negative rail for bipolar supplies. Total V+ to V- must not exceed 7.5 V (absolute maximum).
5 VIN+B input Channel B non-inverting differential signal input. High-impedance CMOS input, 0.5 pA typical bias current.
6 VIN-B input Channel B inverting differential signal input. Diode-clamped to the supply rails; external signals must be current-limited to ≤10 mA if driven >0.5 V beyond the rails.
7 RGB passive Channel B external gain-set resistor node. Connect resistors R1/R2 to set gain per G = 5 + 5(R2/R1); leave open for the internal G = 5 configuration.
8 ShutdownB input Channel B shutdown control (active-low). Drive low (V_SD < 0.8 V) to shut down channel B (I_SD ≈ 0.01 µA typ); drive high (V_SD > 2.5 V) for normal operation. Channel returns to normal within microseconds.
9 VOUTB output Channel B rail-to-rail analog output. Swings to within 0.02 V of V+ (at G ≥ 10) and drives capacitive loads; short-circuit current +48/−32 mA typical.
10 REFB input Channel B output reference/offset input. The channel B output is referenced to this pin; commonly tied to mid-supply (V+/2) for single-supply bipolar signals, or to ground for unipolar signals.
11 V+ power_in Positive supply for both channels. Specified 2.7 V to 5.5 V (operating 2.5 V to 5.5 V); quiescent current 415 µA/channel typ, 490 µA max.
12 REFA input Channel A output reference/offset input. The channel A output is referenced to this pin; commonly tied to mid-supply (V+/2) for single-supply bipolar signals, or to ground for unipolar signals.
13 VOUTA output Channel A rail-to-rail analog output. Swings to within 0.02 V of V+ (at G ≥ 10) and drives capacitive loads; short-circuit current +48/−32 mA typical.
14 ShutdownA input Channel A shutdown control (active-low). Drive low (V_SD < 0.8 V) to shut down channel A (I_SD ≈ 0.01 µA typ); drive high (V_SD > 2.5 V) for normal operation.
