Analog Devices · Operational Amplifier · SOIC-8

AD8031ARZ-REEL7 from Analog Devices, 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 NC unconnected No connect; the datasheet marks this pin NC = NO CONNECT in the AD8031 8-lead SOIC_N diagram.
2 -IN input Inverting input of the single amplifier; the input common-mode range extends beyond the rails by 200 mV per the Features list, while the General Description states the input range can extend to 500 mV beyond each rail.
3 +IN input Non-inverting input of the single amplifier; the input common-mode range extends beyond the rails by 200 mV per the Features list, while the General Description states the input range can extend to 500 mV beyond each rail.
4 -VS power_in Negative supply rail; the part operates from a single +2.7 V to +12 V supply or dual supplies up to ±6 V, with the output swinging to within 20 mV of each rail.
5 NC unconnected No connect; the datasheet marks this pin NC = NO CONNECT in the AD8031 8-lead SOIC_N diagram.
6 OUT output Amplifier output, rated for 15 mA output current and swinging to within 20 mV of either supply rail.
7 +VS power_in Positive supply rail; the part operates from a single +2.7 V to +12 V supply or dual supplies up to ±6 V.
8 NC unconnected No connect; the datasheet marks this pin NC = NO CONNECT in the AD8031 8-lead SOIC_N diagram.
