Texas Instruments · Instrumentation Amplifiers · PDIP-8

INA118PB 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: for gains greater than 1, a gain resistor is placed between pin 1 and pin 8 (gain G = 1 + 50 kΩ / RG).
2 V-IN power_in Negative (inverting) input of the instrumentation amplifier.
3 V+IN power_in Positive (non-inverting) input of the instrumentation amplifier.
4 V- power_in Negative power supply; the device operates from ±2.25 V to ±18 V supplies (recommended VS range ±2.25 to ±18 V, absolute maximum ±18 V).
5 Ref input Reference input that must be driven by a low-impedance source or connected to ground, since the output is referred to this pin.
6 VO output Amplifier output, referred to the Ref pin.
7 V+ power_in Positive power supply; the device operates from ±2.25 V to ±18 V supplies (recommended VS range ±2.25 to ±18 V, absolute maximum ±18 V).
8 RG passive Gain-setting pin: for gains greater than 1, a gain resistor is placed between pin 8 and pin 1 (gain G = 1 + 50 kΩ / RG).
