DESCRIPTION

POBCTRL

Bias Source for Output Amplifiers

0 = Output amplifiers use master bias

1 = Output amplifiers use fast bias

VMIDTOG

VMID Power Down Characteristic

0 = Slow ramp

1 = Fast ramp

FAST_EN

Fast Bias Enable

0 = Fast bias disabled

1 = Fast bias enabled

BUFIO_

VMID Buffer Enable

0 = VMID Buffer disabled

1 = VMID Buffer enabled

SOFT_ST

VMID Soft Ramp Enable

0 = Soft ramp disabled

1 = Soft ramp enabled

BIAS_EN

Master Bias Enable

0 = Master bias disabled

1 = Master bias enabled

Also powers down ADCVMID

R35

BIAS

VMID_

SEL[1:0]

VMID Resistor String Value Selection

(DACVMID only)

00 = off (no VMID)

01 = 100k

10 = 500k

11 = 10k

The selection is the total resistance of the

string from DACREFP to DACREFN. The

ADCVMID resistance is fixed at 200kΩ.
