alternative to MCP6D11T-E/MS

Other Parts Discussed in Thread: THS4551

Hello team,

I used the Tool provided on our website but I didn't get a match. Could you please advise me on an alternative part number to the MCP6D11T-E/MS?

The need here is for a differential opamp either one differential or due opamps integrated in the same package. Rail to Rail both input and output; some protection are needed at the inputs; will be probably used as front end on each channel of the TLV320ADC3410.

Please let me know if you have any solution.

Thank you and best regards,

Adrian

Hey Adrian,

The THS4551 should meet your specs. None of our FDA parts are Rail-to-Rail input, but this part has a negative rail input similar to the MCP6D11T. The abs max ratings for the input of the THS4551 is also better than that of the MCP6D11T.

So actually the max supply on the MCP6D11 is 0.5V higher than the THS4551.

RRinput is almost never required in these FDA ckts and these two parts are negative rail in only,

The only RRinput FDA is the LTC6362 - almost never used where their LTC6363 is more common,

Hello Michael,

I was referring to the Input/Output voltage range rating where the THS4551 can exceed either supply by 0.5V. Assuming the same supply voltages are used for both parts, THS4551 has greater headroom.
