AD623ARMZ-REEL7 from Analog Devices, in a MSOP-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 −RG passive Inverting terminal of external gain-setting resistor RG; with pin 8 forms gain network G = 1 + (100 kΩ/RG).
2 −IN input Inverting in-amp input; input impedance 2 GΩ
3 +IN input Noninverting in-amp input; input impedance 2 GΩ
4 −VS power_in Negative supply terminal; accepts voltage from −6 V to 0 V (single supply) or −2.5 V to −6 V (dual supply).
5 REF input In-amp output reference input; voltage input (−VS to +VS) establishes the common-mode voltage of the output; input impedance 100 kΩ ± 20%.
6 OUTPUT output In-amp output; provides rail-to-rail output swing within 0.2 V of supplies (RL = 10 kΩ).
7 +VS power_in Positive supply terminal; accepts voltage from +3 V to +12 V (single supply) or +2.5 V to +6 V (dual supply).
8 +RG passive Noninverting terminal of external gain-setting resistor RG; with pin 1 forms gain network G = 1 + (100 kΩ/RG).
