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 (R
external buffer. The AD5546/AD5556 are packaged in compact
TSSOP-28 packages with operating temperatures from –40°C to
+125°C.
