Description

A

IN

A

IN

13, 14

Differential input with a common mode voltage of +2.4V. The ADC

full scale input is 1.024 V

signals.

ENCODE

ENCODE

9, 10

Differential clock where ENCODE initiates a new data conversion

cycle on each rising edge. Logic for these inputs are a 50% duty

cycle differential PECL signal.

VCM

21

Internal common mode voltage reference. Nominally +2.4V. Can

be used for the input common mode voltage. This voltage is

derived from an internal bandgap reference.

D0–D11

30–34,

39–45

Digital data outputs are CMOS and TTL compatible. D0 is the LSB

and D11 is the MSB. MSB is inverted. Output coding is two’s

complement.

GND

1–4, 8, 11, 12, 15, 19,

20, 23–26, 35, 36, 47, 48

Circuit ground.

+AV

CC

5–7, 16–18, 22

+5V power supply for the analog section. Bypass to ground with a

0.1 µF capacitor.

+DV

CC

37, 38, 46

+5V power supply for the digital section. Bypass to ground with a

0.1 µF capacitor.
