40

D12B

Channel B CMOS Digital Output, Bit 12

41

D13B

Channel B CMOS Digital Output, Bit 13 (MSB)

42

DORB

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

59

DORA

Channel A Data Out-of-Range Indicator. The DORA digital output indicates when the channel A analog
input voltage is out of range.
DORA = 1: Digital outputs exceed full-scale range.
DORA = 0: Digital outputs are within full-scale range.

64
