TABLE 1. PIN DESCRIPTIONS

PIN NUMBER

NAME

DESCRIPTION

1-10

D0 - D9

Three-State outputs for data bits representing 20 (LSB) through 29 (MSB).

11

DRDY

Output flag signifying new data is available. Goes high at end of clock period 13, goes low when new conversion

started. Also reset asynchronously by DRST.

12

VSS

Digital Ground.

13

DRST

Active low input, resets DRDY.

14

OEM

Active low input, three-state enable of D2 - D9.

15

OEL

Active low input, three-state enable of D0, D1.

16

VAA-

Analog Ground.

17

VAA+

Analog + Supply.

18

VREF-

Reference input voltage, sets 0 code (-) end of input range.

19

STRT

Active Low Start Conversion Input. Recognized after end of clock period 13.

20

CLK

Clock input or output. Conversion functions are synchronous to high-going edge.

21

REXT

Clock adjust input when using internal clock.

22

VREF+

Reference input voltage, set 1023 code (+) end of input range.

23

VlN

Analog Input.

24

VDD

Digital + Supply.
