INA101ASOIC8

analogysemi · Instrumentation OpAmps · SOIC-8

INA101ASOIC8 from analogysemi, in a SOIC-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; connect a resistor between pin 1 and pin 8 to set gain G = 1 + 49.4kΩ/RG (leave open for G = 1).
2 -IN input Inverting signal input; input voltage range is -VS + 0.1V to +VS - 2V, and a series resistor should limit current to 10mA for overvoltage.
3 +IN input Non-inverting signal input; input voltage range is -VS + 0.1V to +VS - 2V, and a series resistor should limit current to 10mA for overvoltage.
4 -VS power_in Negative power supply; split-supply operating range is ±2V to ±19V.
5 REF input Output reference voltage input that sets zero output level; connect to ground or a low-resistance source, with 40kΩ input resistance and range -VS to +VS.
6 OUTPUT output Amplifier output with short-circuit current of ±17mA and swing of within 0.2V of the supply rails (RL = 10kΩ).
7 +VS power_in Positive power supply; split-supply operating range is ±2V to ±19V, absolute maximum ±20V.
8 RG passive Gain-setting pin; connect a resistor between pin 8 and pin 1 to set gain G = 1 + 49.4kΩ/RG (leave open for G = 1).
