OPA4180: OPA4180: Single supply (0V-5V)

Andres Arribas

Part Number: OPA4180

Hello,

Is it possible to use the OPA4180IPW amplifiers with sincle supply?. I mean 5v to the VCC+ pin and GND to VCC- to work with positive signal from 0V to 5V.

Thank you.

Hi Andres,

You may use 5Vdc, single supply rail to power OPA4180 (the minimum is 4Vdc for a single supply). You need to watch for the input common mode range and how to bias your input signal. Enclosed is a simple example.

OPA2180 5V 05232022.TSC

If you have additional questions, please let us know.

Best,

Raymond
