GENERAL DESCRIPTION

The AD5543-EP is a precision 16-bit, low power, current

output, small form factor digital-to-analog converter (DAC). It

is designed to operate from a single 5 V supply with a ±10 V

multiplying reference.

The applied external reference, VREF, determines the full-scale

output current. An internal feedback resistor (RFB) facilitates the

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-EP is packaged in an ultracompact (3 mm × 4.7 mm)

8-lead MSOP package.

Full details about this enhanced product are available in the

AD5543 data sheet, which should be consulted in conjunction

with this data sheet.
