NAME

DESCRIPTION

15–9

Unused.

8

PWRA2D

Power for ADC: 1 = power enabled, 0 = disabled.

7–6

Unused.

5

PWRDAC2

Power for DAC2 in DOP2: 1 = power enabled, 0 = disabled.

4

PWRDAC1

Power for DAC1 in DOP1: 1 = power enabled, 0 = disabled.

3–2

Unused.

1

PWROP2

Power for both large and small op amps in DOP2: 1 = power enabled, 0 = disabled, op-amp
outputs are high impedance.*

0

PWROP1

Power for both LG and SM op amps in DOP1: 1 = power enabled, 0 = disabled, op-amp outputs
are high impedance.*

Table 33. Power-On Control (Address = 31h)

*Whenever the DACs are enabled, the large and/or small op amps are automatically powered up and configured as buffers, regard-
less of the state of the PWROPn and BUFn bits.
