Part Number: TLV9302

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.
