Pin Description (continued)

NAME FUNCTION

D2 Bit 2

TEST2

Test Pin 2. Leave unconnected.

TEST3

Test Pin 3. Leave unconnected.

D0 Bit 0 (LSB)

D1 Bit 1

TEST1

Test Pin 1. Leave unconnected.

Digital Power Supply, +3V to +5.25V.

CLK Input Clock. Receives power from AV

to reduce jitter.

DAV

Data Valid Clock. Digital Output. This clock can be used to transfer the data to a memory or any

other data-acquisition system.

Output Enable: Digital Input.

OE = 0: D0–D13 and DOR are high impedance.

OE = 1: All bits are active.

TEST0

Test Pin 0. Leave unconnected.

Common-Mode Voltage. Analog Input. Drive midway between positive and negative reference

voltages.

RFPF Positive Reference Voltage. Force Input.

RFPS Positive Reference Voltage. Sense Input.

RFNF Negative Reference Voltage. Force Input.

27, 30

RFNS Negative Reference Voltage, Sense Input.

INP Positive Input Voltage

N.C. Not Connected. No internal connection.

41, 42

INN Negative Input Voltage

END_CAL

Digital Output for End of Calibration.

END_CAL = 0: Calibration in progress.

END_CAL = 1: Normal conversion mode.
