ADA4051-2ARMZ-R7

Analog Devices · Precision Op Amps · MSOP-8

ADA4051-2ARMZ-R7 from Analog Devices, 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 OUT A output Output of amplifier A, which is rail-to-rail; the datasheet gives a short-circuit current of 13 mA at VSY = 1.8 V.
2 -IN A input Inverting input of amplifier A; the input voltage should stay within ±VSY ± 0.3 V, and the voltage difference between the two inputs must not exceed ±VSY.
3 +IN A input Non-inverting input of amplifier A; the input voltage should stay within ±VSY ± 0.3 V, and the voltage difference between the two inputs must not exceed ±VSY.
4 V- power_in Negative supply pin; the amplifiers are powered from a single supply of 1.8 V to 5.5 V, with a 6 V absolute maximum supply voltage.
5 +IN B input Non-inverting input of amplifier B; the input voltage should stay within ±VSY ± 0.3 V, and the voltage difference between the two inputs must not exceed ±VSY.
6 -IN B input Inverting input of amplifier B; the input voltage should stay within ±VSY ± 0.3 V, and the voltage difference between the two inputs must not exceed ±VSY.
7 OUT B output Output of amplifier B, which is rail-to-rail; the datasheet gives a short-circuit current of 13 mA at VSY = 1.8 V.
8 V+ power_in Positive supply pin; the amplifiers are powered from a single supply of 1.8 V to 5.5 V, with a 6 V absolute maximum supply voltage.
