PRODUCT OVERVIEW

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

to-analog converters designed to operate from a 4.5 V to 5.5 V

supply range.

An external reference is needed to establish the full-scale

output-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

LDAC

chip select ( ). Additional

function allows

simultaneous 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.
