Power Supply

The EVM accepts four power supplies.

-A dual ± Vs dc supply for the dual-supply op-amps.

-A single 5.0 V dc supply for the analog section of the ADC.

-A single 3.3 V to 5 V dc supply for the digital section of the ADC. There are two ways to provide these voltages.

-Hook-up the test points on the EVM. The test points are clearly labeled +Vdd (3.3 V to 5 V), +5VA, +Vs (up to 18 V depending upon the amplifiers) and –Vs (up to –18 V depending upon the amplifiers).

-Use the power connector P5/J5 and derive the voltages elsewhere. The pinout for this connector is shown in Table 4− 1.
