15 0 Rx Analog Bias Power-Down. “0” = active; “1” = Power-Down
14 0 RxRef Power-Down. “0” = active; “1” = Power-Down
13 0 DiffRef Power-Down. “0” = active; “1” = Power-Down
12 0 VREF Power-Down. “0” = active; “1” = Power-Down
7 0 Rx_B Analog Power-Down. “0” = active; “1” = Power-down
6 0 Rx_B DC Bias Power-Down. “0” = active; “1” = Power-down
This register is used to set Rx Path of ADDAC A.

Reconfigurable bits:
Bit Default Description
13 0 Rx_B 2‟s complement. “0” = straight binary; “1” = 2‟s complement
12 0 Rx_B Clk Duty. “0” = disable; “1” = enable
5 0 Rx_A 2‟s complement. “0” = straight binary; “1” = 2‟s complement
4 0 Rx_A Clk Duty. “0” = disable; “1” = enable
This register is used to set Ultra low power control of Rx path of ADDAC A, in
combination with asserting the ADC_LO_PWR pin to reduce power consumption.
