PIN NAME FUNCTION
30 D0B Channel B CMOS Digital Output, Bit 0 (LSB)
31 D1B Channel B CMOS Digital Output, Bit 1
32 D2B Channel B CMOS Digital Output, Bit 2
33 D3B Channel B CMOS Digital Output, Bit 3
34 D4B Channel B CMOS Digital Output, Bit 4
35 D5B Channel B CMOS Digital Output, Bit 5
36 D6B Channel B CMOS Digital Output, Bit 6
37 D7B Channel B CMOS Digital Output, Bit 7
38 D8B Channel B CMOS Digital Output, Bit 8
39 D9B Channel B CMOS Digital Output, Bit 9
40 D10B Channel B CMOS Digital Output, Bit 10
41 D11B Channel B CMOS Digital Output, Bit 11 (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 MAX12527 evaluation kit (MAX12557 EV kit) utilizes DAV to latch data into any external back-end
digital logic.
47 D0A Channel A CMOS Digital Output, Bit 0 (LSB)
48 D1A Channel A CMOS Digital Output, Bit 1
49 D2A Channel A CMOS Digital Output, Bit 2
50 D3A Channel A CMOS Digital Output, Bit 3
51 D4A Channel A CMOS Digital Output, Bit 4
52 D5A Channel A CMOS Digital Output, Bit 5
53 D6A Channel A CMOS Digital Output, Bit 6
54 D7A Channel A CMOS Digital Output, Bit 7
55 D8A Channel A CMOS Digital Output, Bit 8
56 D9A Channel A CMOS Digital Output, Bit 9
57 D10A Channel A CMOS Digital Output, Bit 10
58 D11A Channel A CMOS Digital Output, Bit 11 (MSB)
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 G/T
Output Format Select Digital Input.
G/T = GND: Two’s-complement output format selected.
G/T = OV
DD
: Gray-code output format selected.
65 PD
Power-Down Digital Input.
PD = GND: ADCs are fully operational.
PD = OV
DD
: ADCs are powered down.
