Pin Description (continued)
PIN NAME FUNCTION
50 D4N Complementary Output Bit 4
51 D4P True Output Bit 4
52 D5N Complementary Output Bit 5
53 D5P True Output Bit 5
54 D6N Complementary Output Bit 6
55 D6P True Output Bit 6
56 D7N Complementary Output Bit 7
57 D7P True Output Bit 7
58 ORN
Complementary Output for Out-of-Range Control Bit. If an out-of-range condition is detected,
bit ORN flags this condition by transitioning low.
59 ORP
True Output for Out-of-Range Control Bit. If an out-of-range condition is detected, bit ORP
flags this condition by transitioning high.
68 T/B
Two’s Complement or Binary Output Format Selection. This LVCMOS-compatible input
controls the digital output format of the MAX1121.
T/B has an internal pulldown resistor.
T/B = 0: Two’s complement output format
T/B = 1: Binary output format
