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.
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/AD5553 are packaged in ultracompact (3 mm ×
4.7 mm) 8-lead MSOP and 8-lead SOIC packages.
