s PIN ASSIGNMENT

s PIN DESCRIPTION

Values within ( ) are typical values.

s NOTES ON USE

• Be sure to bypass the AVDD, DVDD, VRT and VRB pins to the ground using a high-frequency capacitor.

The high-frequency capacitor should be connected as near the pin as possible.

• Provide four clocks or more immediately after the power up to prevent current dissipation due to the

indeterminate internal logic.

Pin No.

Pin name

Functions

1, 2, 16, 18

AVDD

Analog power supply pins (+5 V)

DVDD

Digital power supply pin (+3 or +5 V)

3, 15, 17, 24

AVSS

Analog power ground pins (0 V)

DVSS

Digital power ground pin (0 V)

4 to 11

D1 to D8

Digital output pins. D1: MSB, D8: LSB

CLK

Clock input pin

VINA

Analog input pin. Input range: VRB to VRT (2 Vp-p between 0.5 to 3 V)

VRT

Reference voltage input pin (3 V)

VREFT

Reference voltage output pin. When connected to VRT, the pin generates

0.6

× AVDD (3 V).

VRB

Reference voltage input pin (1 V)

VREFB

Reference voltage output pin. When connected to VRB, the pin generates

0.2

× AVDD (1 V).
