AD8657ARMZ-R7

Analog Devices · Operational Amplifier · MSOP-8

AD8657ARMZ-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 channel A; the datasheet describes the AD8657 as having rail-to-rail input and output.
2 -IN A input Negative (inverting) input of channel A.
3 +IN A input Positive (noninverting) input of channel A, which the datasheet specifies for EMIRR of 90 dB typical at 400 MHz to 2400 MHz.
4 V- power_in Negative supply voltage; the datasheet gives a single-supply range of 2.7 V to 18 V, or dual supply of ±1.35 V to ±9 V.
5 +IN B input Positive (noninverting) input of channel B.
6 -IN B input Negative (inverting) input of channel B.
7 OUT B output Output of channel B; the datasheet describes the AD8657 as having rail-to-rail input and output.
8 V+ power_in Positive supply voltage; the absolute maximum supply voltage is 20.5 V.
