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. |
