Jacky,

Sorry for not responding, but the US is on holiday today.

The ADS1194 is a 16-bit version of the ADS1294 and should be less expensive.

Hola Joseph,
Thank you for the prompt reply and we still need to keep 24-bit with 3-channel ADC for our application,
so do you have another solution which less expensive with ADS1294？Thank you ～

Jacky,

Perhaps you should wait for someone more familiar with this product space to answer this question tomorrow, but I don't think there are any other devices that simultaneously samples multiple channels designed for this application.

The only other option that I can think of would be to use an ADS1291 but use a front end multiplexer to get multiple channels.
