GENERAL DESCRIPTION
The AD5546/AD5556 are precision 16-/14-bit, multiplying, low
power, current output, parallel input digital-to-analog converters
(DACs). They operate from a single 2.7 V to 5.5 V supply with
±10 V multiplying references for four-quadrant outputs. Built-
in four-quadrant resistors facilitate the resistance matching and
temperature tracking that minimize the number of components
needed for multiquadrant applications. The feedback resistor
(RFB) simplifies the I-V conversion with an external buffer. The
AD5546/AD5556 are packaged in compact TSSOP-28 packages
with operating temperatures from –40°C to +125°C.
The EVAL-AD5546SDZ is available for evaluating DAC perfor-
mance. For more information, see the UG-309 evaluation board
user guide.
