AD5551/AD5552

–4–

REV. 0

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily

accumulate on the human body and test equipment and can discharge without detection. Although

the AD5551/AD5552 features proprietary ESD protection circuitry, permanent damage may occur

on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions

are recommended to avoid performance degradation or loss of functionality.

AD5551 PIN FUNCTION DESCRIPTIONS

Mnemonic

Pin No.

Description

1

Analog Output Voltage from the DAC.

AGND

2

Ground Reference Point for Analog Circuitry.

3

This is the voltage reference input for the DAC. Connect to external reference ranges from

CS

4

This is an active low-logic input signal. The chip select signal is used to frame the serial

data input.

SCLK

5

Clock Input. Data is clocked into the input register on the rising edge of SCLK. Duty cycle

must be between 40% and 60%.

DIN

6

Serial Data Input. This device accepts 14-bit words. Data is clocked into the input register on

the rising edge of SCLK.

DGND

7

Digital Ground. Ground reference for digital circuitry.

8

Analog Supply Voltage, 5 V

± 10%.
