Power Supply Recommendations

The ADS1204 requires two power supplies, AVDD for analog, and BVDD for digital. The analog supply is a fixed voltage of 5 V ± 5%, whereas the digital supply can be set within a range of 2.7 V to 5.5 V. BVDD determines the I/O voltage for the interface. If AVDD equals BVDD, the two supplies can be tied together.
