Channel B Data Out-of-Range Indicator. The DORB digital output indicates when the channel B analog

42

DORB

input voltage is out of range.

DORB = 1: Digital outputs exceed full-scale range.

 

 

 

 

DORB = 0: Digital outputs are within full-scale range.

 

 

 

 

 

 

 

Data-Valid Digital Output. The rising edge of DAV indicates that data is present on the digital outputs.

44

DAV

The MAX12527 evaluation kit (MAX12557 EV kit) utilizes DAV to latch data into any external back-end

 

 

digital logic.

47

D0A

57

D10A

Channel A CMOS Digital Output, Bit 10

 

 

 

 

 

58

D11A

Channel A CMOS Digital Output, Bit 11 (MSB)

 

 

 

 

 

 

 

Channel A Data Out-of-Range Indicator. The DORA digital output indicates when the channel A analog

59

DORA

input voltage is out of range.

DORA = 1: Digital outputs exceed full-scale range.

 

 

 

 

DORA = 0: Digital outputs are within full-scale range.

 

 

Output Format Select Digital Input.

64

G/T

G/T = GND: Two’s-complement output format selected.

 

 

G/T = OVDD: Gray-code output format selected.

 

 

Power-Down Digital Input.

65

PD

PD = GND: ADCs are fully operational.

 

 

PD = OVDD: ADCs are powered down.
