INA129P

Texas Instruments · Instrumentation Amplifiers · PDIP-8

INA129P from Texas Instruments, in a PDIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RG passive Gain setting pin; connect external resistor between pins 1 and 8 to program gain according to formula G = 1 + 49.4kΩ/RG.
2 VIN- power_in Inverting input pin accepting common-mode voltage from (V-) + 2V to (V+) - 2V with maximum safe input voltage of ±40V.
3 VIN+ power_in Non-inverting input pin accepting common-mode voltage from (V-) + 2V to (V+) - 2V with maximum safe input voltage of ±40V.
4 V- power_in Negative power supply pin; supply voltage range ±2.25V to ±18V dual supply or 4.5V to 36V single supply.
5 REF input Reference input pin that must be driven by low impedance source; output voltage is referenced to this pin and is typically connected to ground.
6 VO output Output pin providing amplified differential voltage with output swing from (V-) + 1.4V to (V+) - 1.4V for CSO:SHE or (V-) + 0.15V to (V+) - 0.15V for CSO:FRE.
7 V+ power_in Positive power supply pin; supply voltage range ±2.25V to ±18V dual supply or 4.5V to 36V single supply.
8 RG passive Gain setting pin; connect external resistor between pins 1 and 8 to program gain according to formula G = 1 + 49.4kΩ/RG.
