Maxim Integrated · Operational Amplifier · MSOP-8

MAX4477AUA+ from Maxim Integrated, in a MSOP-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 Amplifier A output, a rail-to-rail output that drives loads as low as 1kΩ and capacitive loads up to 200pF without oscillation.
2 INA- input Amplifier A inverting input, with an input common-mode range of VSS - 0.2V to VDD - 1.6V at +25°C.
3 INA+ input Amplifier A noninverting input, with an input common-mode range of VSS - 0.2V to VDD - 1.6V at +25°C.
4 VSS power_in Negative supply, connected to ground for single-supply operation.
5 INB+ input Amplifier B noninverting input, with an input common-mode range of VSS - 0.2V to VDD - 1.6V at +25°C.
6 INB- input Amplifier B inverting input, with an input common-mode range of VSS - 0.2V to VDD - 1.6V at +25°C.
7 OUTB output Amplifier B output, a rail-to-rail output that drives loads as low as 1kΩ and capacitive loads up to 200pF without oscillation.
8 VDD power_in Positive supply, operating from +2.7V to +5.5V and bypassed with a 0.1µF ceramic capacitor placed close to the pin.
