INA849DR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 -IN input Negative (inverting) differential signal input. Input range is (-VS)-0.5 V to (+VS)+0.5 V; must operate within the specified VCM range of (-VS)+2.5 V to (+VS)-2.5 V.
2 RG passive Gain-setting pin. Place an external gain resistor RG between pin 2 and pin 3 to set gain G = 1 + (6 kΩ / RG); leave open for G = 1.
3 RG passive Gain-setting pin. Place an external gain resistor RG between pin 2 and pin 3 to set gain G = 1 + (6 kΩ / RG); leave open for G = 1.
4 +IN input Positive (noninverting) differential signal input. Input range is (-VS)-0.5 V to (+VS)+0.5 V; must operate within the specified VCM range of (-VS)+2.5 V to (+VS)-2.5 V.
5 -VS power_in Negative supply rail. For dual supply operation ±4 V to ±18 V, or tie to ground for single-supply operation (8 V to 36 V on +VS). Bypass to ground with a 100 nF capacitor close to the pin.
6 REF input Reference input. Sets the output DC level: VO = G·(V+IN - V-IN) + VREF. Must be driven by a low-impedance source; input range is (-VS)-0.5 V to (+VS)+0.5 V.
7 OUT output Amplifier output. Rail-to-rail-ish voltage swing to within 150 mV of the supplies with RL = 10 kΩ; short-circuit current ±34 mA typical; drives loads to VS/2 continuously.
8 +VS power_in Positive supply rail. Single supply 8 V to 36 V, or dual supply ±4 V to ±18 V referenced to -VS. Bypass to ground (or to -VS) with a 100 nF capacitor close to the pin.
