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.

 

 

 

 

 

44

DAV

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

The MAX12557 evaluation kit utilizes DAV to latch data into any external back-end digital logic.

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.
