INA117P 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 | RefB | input | Reference B input; in the transfer function V0 = V3 - V2 + 20 × V5 - 19 × V1 it contributes -19 × V1, and a series resistor on this pin reduces CMRR (4 Ω reduces it from 86 dB to 72 dB). |
| 2 | -In | input | Inverting signal input; signal inputs withstand ±200 V continuous common-mode (±500 V peak for 0.1 s), and a series resistor above 75 Ω reduces CMR from 86 dB to 72 dB. |
| 3 | +In | input | Non-inverting signal input; in the basic unit-gain configuration the output equals V3 - V2, and signal inputs withstand ±200 V continuous common-mode. |
| 4 | V- | power_in | Negative power supply; recommended range is ±5 V to ±18 V for dual supply or 10 V to 36 V for single supply, with an absolute maximum of ±22 V across V+ and V-. |
| 5 | RefA | input | Reference A input; in the transfer function V0 = V3 - V2 + 20 × V5 - 19 × V1 it contributes +20 × V5, and a series resistor on this pin reduces CMRR (4 Ω reduces it from 86 dB to 72 dB). |
| 6 | Output | output | Amplifier output; in the basic unit-gain configuration it equals the differential input voltage between pins 2 and 3 (V0 = V3 - V2). |
| 7 | V+ | power_in | Positive power supply; recommended range is ±5 V to ±18 V for dual supply or 10 V to 36 V for single supply, with an absolute maximum of ±22 V across V+ and V-. |
| 8 | NC | unconnected | No internal connection; may be grounded or left unconnected. |
