OPA2145: alternative for OP213FSZ.

Wouter Kragt

Part Number: OPA2145

Hello team,

While searching, I found the OPA2145IDR as an alternative for OP213FSZ.

The test results look good so far, but I wanted to check there are any risks associated with its use or if you also consider the OPA2145IDR to be a viable second-source option?

Kind regards,

Hello,

The recommended options are shown below. The noise is higher on both replacements so tha may or may not be a concern. The gain bandwidth is higher on the recommended replacements so stability should be considered if large capacitive loads are being driven. Where the replacements accel is in slew rate, bias current and lower Iq. There are no other recommended alternatives outside of what is listed below.
