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.
