INA823DR from Texas Instruments, 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; place external gain resistor between pin 1 and pin 8 to set gain according to G = 1 + (100 kΩ / RG). |
| 2 | -IN | input | Negative (inverting) input with ±60-V overvoltage protection; input voltage range (-VS) - 0.15 V to (+VS) - 1 V at common-mode. |
| 3 | +IN | input | Positive (noninverting) input with ±60-V overvoltage protection; input voltage range (-VS) - 0.15 V to (+VS) - 1 V at common-mode. |
| 4 | -VS | power_in | Negative supply; operating range ±1.35 V to ±18 V for dual-supply mode or ground reference for single-supply mode up to 36 V. |
| 5 | REF | input | Reference input; must be driven by low impedance source with voltage (-VS) to (+VS); output referred to this pin with 1-V/V gain. |
| 6 | OUT | output | Output with voltage swing (-VS) + 0.15 V to (+VS) - 0.15 V, short-circuit current ±20 mA continuous to VS/2. |
| 7 | +VS | power_in | Positive supply; operating range 2.7 V to 36 V for single supply or ±1.35 V to ±18 V for dual-supply mode. |
| 8 | RG | passive | Gain setting pin; place external gain resistor between pin 1 and pin 8 to set gain according to G = 1 + (100 kΩ / RG). |
