Hi Team,

a customer is looking for a replacement of MCP3564RT-E/ST which is used to read out a wheatstone bridge.

I found ADS1260/1 but I wanted to check with you if you would recommend any other solution.

Requirements:
24 bit
Integrated amplifier
VREF ~2.4V (max 3.3)
differential input

BR,
Stefan

Hi Stefan,

the ADS1260/61 would be our highest accuracy, highest resolution and fastest ADCs for Wheatstone bridge measurements and a suitable alternative to MCP3564.
If you don't need an internal VREF, then ADS1235 would be a lower-cost option with the same performance.

Note that those ADCs require a 5V analog supply. If you need an ADC that operates at 3.3V, then you may want to look at ADS124S06/08.

If you have not seen it yet, please also share some of our great collateral around bridge measurements:

Joachim Wuerker
