Power Supply Arrangements

The CS5529 is designed to operate from single or

dual analog supplies and a single digital supply.

The following power supply connections are possi-

ble:

VA+ = +5 V; VA- = 0 V; VD+ = +3 V to +5 V

VA+ = +2.5 V; VA- = -2.5 V; VD+ = +3 V to +5 V

VA+ = +3.0 V; VA- = -3.0 V; VD+ = +3 V

Figure 10 illustrates the CS5529 connected with a

single +5 V supply to measure differential inputs

relative to a common mode of 2.5 V. Figure 11 il-

lustrates the CS5529 connected with ±2.5 V bipolar
