ADA4528-1ARMZ-R7

Analog Devices · Precision Op Amps · MSOP-8

ADA4528-1ARMZ-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 NIC unconnected No internal connection; the pin is not connected inside the device and can be left unconnected.
2 -IN input Inverting input of the amplifier, with input voltage range 0 V to 5 V at 5 V supply and 0 V to 2.5 V at 2.5 V supply.
3 +IN input Non-inverting input of the amplifier, with input voltage range 0 V to 5 V at 5 V supply and 0 V to 2.5 V at 2.5 V supply.
4 V- power_in Negative power supply voltage; the device runs from 2.2 V to 5.5 V single supply, or ±1.1 V to ±2.75 V dual supply, with absolute maximum total supply of 6 V.
5 NIC unconnected No internal connection; the pin is not connected inside the device and can be left unconnected.
6 OUT output Amplifier output, which swings close to both supply rails with rail-to-rail output.
7 V+ power_in Positive power supply voltage; the device runs from 2.2 V to 5.5 V single supply, or ±1.1 V to ±2.75 V dual supply, with absolute maximum total supply of 6 V.
8 NIC unconnected No internal connection; the pin is not connected inside the device and can be left unconnected.
