Additional Details:

The ADS1256IDB operates from a single 5V analog supply and a 3.3V to 5V digital supply. It features a flexible input multiplexer that can be configured for either six differential or eight single-ended input channels. The integrated PGA allows for direct connection to low-level signals, eliminating the need for external amplification in many applications. The digital filter provides excellent noise rejection, further enhancing the accuracy of the measurements. The device is available in a small TSSOP-24 package, making it suitable for space-constrained applications.
