TERMINAL

DESCRIPTION

NAME

NO.

AIN

16

Differential input signal (positive)

AIN

17

Differential input signal (negative)

3, 8, 13, 14, 19, 21,

AVDD5

Analog power supply (5 V)

23, 25, 27, 31

Analog power supply (3.3 V) (Suggestion for

≤250 MSPS: leave option to connect to 5 V for

AVDD3

35, 37, 39

ADS5440/4 13-bit compatibility)

DVDD3

1, 51, 66

Output driver power supply (3.3 V)

2, 7, 9, 12, 15, 18,

20, 22, 24, 26, 28,

GND

Ground

30, 32, 34, 36, 38,

40, 52, 65

CLK

10

Differential input clock (positive). Conversion is initiated on rising edge.

CLK

11

Differential input clock (negative)

D0, D0

54, 53

LVDS digital output pair, least-significant bit (LSB)

D1–D10,

55–64,

LVDS digital output pairs

D1–D10

67–76

D11, D11

78, 77

LVDS digital output pair, most-significant bit (MSB)

DRY, DRY

80, 79

Data ready LVDS output pair

No connect (4 and 5 should be left floating, 43–50 are possible future bit additions for this pinout

NC

4, 5, 43–50

and therefore can be connected to a digital bus or left floating)

Overrange indicator LVDS output. A logic high signals an analog input in excess of the full-scale

OVR, OVR

42, 41

range.

Pin 29 is reserved for possible future Vcm output for this pinout, like ADS5474; pin 33 is reserved for

RESERVED

29, 33

possible future power-down control pin for this pinout, like ADS5474.

VREF

6

Reference voltage input/output (2.4V nominal)
