Pin Description (continued)

PIN NAME FUNCTION

26, 45, 61 OGND Digital Converter Ground. Ground connection for digital circuitry and output drivers.

27, 28, 41, 44, 60

Digital Supply Voltage. Bypass with a 0.1µF capacitor for best decoupling results.

29–32 N.C. No Connection. Do not connect to these pins.

33 D0N Complementary Output Bit 0 (LSB)

34 D0P True Output Bit 0 (LSB)

35 D1N Complementary Output Bit 1

36 D1P True Output Bit 1

37 D2N Complementary Output Bit 2

38 D2P True Output Bit 2

39 D3N Complementary Output Bit 3

40 D3P True Output Bit 3

42 DCLKN

Complementary Clock Output. This output provides an LVDS-compatible output level and can

be used to synchronize external devices to the converter clock. There is a 2.1ns delay

between CLKP and DCLKP.

43 DCLKP

True Clock Output. This output provides an LVDS-compatible output level and can be used to

synchronize external devices to the converter clock. There is a 2.1ns delay between CLKN

and DCLKN.

46 D4N Complementary Output Bit 4

47 D4P True Output Bit 4

48 D5N Complementary Output Bit 5

49 D5P True Output Bit 5

50 D6N Complementary Output Bit 6

51 D6P True Output Bit 6

52 D7N Complementary Output Bit 7

53 D7P True Output Bit 7

54 D8N Complementary Output Bit 8

55 D8P True Output Bit 8

56 D9N Complementary Output Bit 9 (MSB)

57 D9P True Output Bit 9 (MSB)

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 MAX1123. T/B has an internal pulldown resistor.

T/B = 0: Two’s complement output format

T/B = 1: Binary output format
