MAX4477ASA+T

Analog Devices Inc Maxim Integrated · Operational Amplifier · SO-8

MAX4477ASA+T from Analog Devices Inc Maxim Integrated, in a SO-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, rail-to-rail swing that drives loads down to 1kΩ.
2 INA- input Amplifier A inverting input, with a common-mode range from 0.2V below VSS to VDD - 1.6V.
3 INA+ input Amplifier A noninverting input, with a common-mode range from 0.2V below VSS to VDD - 1.6V.
4 VSS power_in Negative supply; connect to ground for single-supply operation.
5 INB+ input Amplifier B noninverting input, with a common-mode range from 0.2V below VSS to VDD - 1.6V.
6 INB- input Amplifier B inverting input, with a common-mode range from 0.2V below VSS to VDD - 1.6V.
7 OUTB output Amplifier B output, rail-to-rail swing that drives loads down to 1kΩ.
8 VDD power_in Positive supply, +2.7V to +5.5V, bypassed with a 0.1µF ceramic capacitor placed close to the pin.
