Other Parts Discussed in Thread: TLV9102, TLV9352, , TLV9152
Hello,
I need to identify replacement op amps for the MC33202, MC33172, and MC33178 devices. What are the best P2P(Pin to Pin) replacement amplifiers from TI?
Thanks!

Hi Katherine,
Consider the TLV9102 or TLV9152 for 16V designs, or if higher voltage is required consider the TLV9302 or TLV9352 for up to a 40V power supply range.
Here is a side by side comparison of the 4 recommended devices.
Here is a table showing the performance differences between MC33202, MC33172, MC33178, and the recommend devices.
