Hi team,

My customer need a faster settling time amp than TLV2171 0.1% 1μs, which used to sensing HVAC DC_link current and get higher sensing precision.

Looking forward to your reply.

The OPA2992 has 0.3 µs. There are high-speed op amps like the OPA2834 or LMH6643 with less than 0.1 µs.

Hi Chen,

Do you know if the OPA2992 would be a fast enough amplifier? Also do you know the customer's settling time target?

Best Regards,

Robert Clifton
