41
D13B Channel B CMOS Digital Output, Bit 13 (MSB)
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.
