ADA4091-2ARZ-R7

Analog Devices · Operational Amplifier · SOIC-8

ADA4091-2ARZ-R7 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 OUTA output Output of amplifier A, which swings rail-to-rail with the final output limit set by a saturation voltage of about 50 mV near either rail.
2 -INA input Inverting input of amplifier A; the input voltage may exceed either supply without phase reversal or latch-up (overvoltage protection), and input current must be limited to ±5 mA.
3 +INA input Non-inverting input of amplifier A; the input voltage may exceed either supply without phase reversal or latch-up (overvoltage protection), and input current must be limited to ±5 mA.
4 -V power_in Negative power supply pin; the part operates from a 3.0 V to 30 V single supply or ±1.5 V to ±15 V dual supplies, with a 36 V absolute maximum supply voltage.
5 +INB input Non-inverting input of amplifier B; the input voltage may exceed either supply without phase reversal or latch-up (overvoltage protection), and input current must be limited to ±5 mA.
6 -INB input Inverting input of amplifier B; the input voltage may exceed either supply without phase reversal or latch-up (overvoltage protection), and input current must be limited to ±5 mA.
7 OUTB output Output of amplifier B, which swings rail-to-rail with the final output limit set by a saturation voltage of about 50 mV near either rail.
8 +V power_in Positive power supply pin; the part operates from a 3.0 V to 30 V single supply or ±1.5 V to ±15 V dual supplies, with a 36 V absolute maximum supply voltage.
