INA156EA

Texas Instruments · Instrumentation Amplifiers · MSOP-8

INA156EA from Texas Instruments, in a MSOP-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 input Gain-setting terminal; leave open for G=10, connect to pin 8 for G=50, or insert external resistor RG per equation G=10+400kΩ/(10kΩ+RG) for intermediate gains.
2 VIN- power_in Inverting input; signal voltage range (V-) - 0.5 to (V+) + 0.5 V with input impedance 1013
3 VIN- power_in Non-inverting input; signal voltage range (V-) - 0.5 to (V+) + 0.5 V with input impedance 1013
4 V- power_in Negative power supply terminal; ground reference in single-supply operation or negative rail in dual-supply operation.
5 Ref input Reference voltage input terminal; typically set to VS/2 for single-supply operation; must be driven from low-impedance source to maintain CMRR minimum 65 dB over temperature.
6 VOUT output Output terminal; rail-to-rail voltage swing within 5 to 20 mV from either supply rail depending on gain configuration and load impedance.
7 V+ power_in Positive power supply terminal; specified supply range +2.7V to +5.5V for guaranteed operation.
8 RG input Gain-setting terminal; connect to pin 1 for G=50, leave open for G=10, or insert external resistor RG per equation G=10+400kΩ/(10kΩ+RG) for intermediate gains.
