Analog Devices · Operational Amplifier · SOIC-8

OP284FSZ 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 OUT A output Output of amplifier A, a rail-to-rail stage that saturates about 20 mV above V- and 100 mV below V+, with a typical short-circuit current limit of about 20 mA.
2 -IN A input Inverting input of amplifier A; the differential input is limited to ±0.6 V, and input current should be kept below 5 mA by a series resistor if overdrive is expected.
3 +IN A input Non-inverting input of amplifier A, with an input voltage range that spans the full supply rails (0 V to 5 V at 5 V supply) and is protected only by external limiting above the rails.
4 V- power_in Negative supply rail; in single-supply operation this pin is tied to GND, and the device operates from 3 V to 36 V total supply.
5 +IN B input Non-inverting input of amplifier B, with the same rail-to-rail input range and the same overdrive limits as the other inputs.
6 -IN B input Inverting input of amplifier B, with a differential input limit of ±0.6 V and an input current limit of 5 mA under overdrive.
7 OUT B output Output of amplifier B, a rail-to-rail stage with the same saturation limits (about 20 mV from V- and 100 mV from V+) and typical short-circuit current of about 20 mA.
8 V+ power_in Positive supply rail; the datasheet guarantees operation from 3 V to 36 V (or ±1.5 V to ±18 V).
