OPA192 instead of MCP6002.

Other Parts Discussed in Thread: OPA192, TLV9002, OPA2392


I want to make this Analog thermostat with relay PCB.

This project uses an MCP6002. Can I use OPA192 by Texas Instruments (  instead of this? 

  • The TLV9002 would be the nearest replacement. The OPA192 has a much higher precision, is faster, and is designed for high voltages, but it would work fine.

  • Zain,

    Here are a few other things to consider:

    1.  You may want to choose a device that is optimized for 5V operation.  The OPA192 is optimized for +/-15V operation.

    2.  You will need to make sure that you use the correct package and number of channels.  MCP6002 is a dual.

    3.  The OPA2392 is similar to OPA192 (package level trim precision), but it has a 5.5V maximum supply.  Also this is a dual (two op amps in one package) similar to MCP6002.  You still need to confirm the correct package.

    4.  Another option is TLV9002.  This device is a lower cost / less accurate device more comparable to MCP6002.
