Description

1

RESET

Asynchronous Reset Pin. Tie this pin high for normal operation. When this pin is brought low, the AD5593R is reset

to its default configuration.

2

A0

Address Input. Sets the LSB of the 7-bit slave address.

3

Power Supply Input. The AD5593R can operate from 2.7 V to 5.5 V. Decouple the supply with a 0.1 μF capacitor to GND.

I/O0 to I/O7

Input/Output 0 Through Input/Output 7. These pins can be independently configured as DACs, ADCs, or general-

purpose digital inputs or outputs. The function of each pin is determined by programming the appropriate bits in

the configuration registers.

8

AD5593R. When the internal reference is disabled, an external reference must be applied to this pin. The voltage

9

Interface Power Supply. The voltage on this pin ranges from 1.8 V to 5.5 V.

14

GND

Ground Reference Point for All Circuitry.

15

SDA

Serial Data Input. This pin is used in conjunction with the SCL line to clock data in to or out of the input shift register. SDA

16

SCL

Serial Clock Line. This pin is used in conjunction with the SDA line to clock data in to or out of the 16-bit input register.
