GENERAL DESCRIPTION

The AD5543/AD5553 are precision 16-/14-bit, low power,

current output, small form factor digital-to-analog converters

(DACs). They are designed to operate from a single 5 V supply

with a ±10 V multiplying reference.

R-2R and temperature tracking for voltage conversion when

combined with an external op amp.

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

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

chip select (CS).

The AD5543/AD5553 are packaged in ultracompact (3 mm ×

4.7 mm) 8-lead MSOP and 8-lead SOIC packages.
