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
