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.
