OPA552: Voltage

Part Number: OPA552

Hi team,

When the OPA552 is noninverting input, does the voltage follower, (about 36V), if its unit gain is stable? Thanks.

The OPA552 is not (guaranteed to be) stable at gains less than 5.

Section 8.2.2.3 suggests a mechanism to make it stable at lower gains, but only in an inverting configuration.

Enhui,

I agree with Clemens (thanks Clemens). The OPA551 is unity gain stable however.

Best regards, Art
