FDAC Register (Reg. 7, Address 000111)
The FDAC register is used to set the Fine Offset DAC in the Manual Calibration mode. See Calibration
Option, in the Black Level Offset Calibration section for more information.
Control Register (Reg. 8, Address 001000)
The Control register is used to set various test and power-down modes.
DIGtest=0, normal operation.
DIGtest=1, Exar test mode - do not use.
ADCtest=0, connects PGA output to ADC input.
ADCtest=1, connects ADCinP & ADCinN pins to ADC input.
NoCDS=0, connects CDS output to PGA input.
NoCDS=1, connects Test1 & Test2 pins to PGA inputs (CDS by-pass mode).
Low Power=0, normal operation.
Low Power=1, Exar test mode - do not use.
OE=0, digital outputs in high-Z state.
OE=1, digital outputs enabled.
DAC1pd=1, Utility DAC1 is powered down.
DAC0pd=1, Utility DAC0 is powered down.
AFEpd=0, normal operation.
AFEpd=1, CDS & PGA are powered down, do not use.
ADCpd=0, normal operation.
ADCpd=1, ADC is powered down, do not use.
PwrDwn=0, normal operation.
PwrDwn=1, the whole chip is powered down.
