INA117P

Texas Instruments · Differential Amplifiers · PDIP-8

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.
