PRODUCT OVERVIEW

The AD5545/AD5555 are 16-bit/14-bit, current-output, digital-

to-analog converters designed to operate from a single 5 V

supply with bipolar output up to 15 V capability.

An external reference is needed to establish the full-scale out-

put-current. An internal feedback resistor (R_FB) enhances the

resistance and temperature tracking when combined with an

external op amp to complete the I-to-V conversion.

A serial data interface offers high speed, 3-wire microcontroller

compatible inputs using serial data in (SDI), clock (CLK), and

chip select ( ). Additional

function allows simultane-

LDAC

ous update operation. The internal reset logic allows power-on

preset and dynamic reset at either zero or midscale, depending

on the state of the MSB pin.

The AD5545/AD5555 are packaged in the compact TSSOP-16

package and can be operated from –40°C to +85°C.
