The AD5547/AD5557 are dual precision, 16-/14-bit,
multiplying, low power, current-output, parallel input, digital-
to-analog converters. They are designed to operate from single
+5 V supply with ±10 V multiplying references for 4-quadrant
outputs with up to 4 MHz bandwidth.

The built-in 4-quadrant resistors facilitate resistance matching
and temperature tracking, which minimize the numbers of
components needed for multiquadrant applications. In addition,
the feedback resistor (RFB) simplifies the I-V conversion with an
The AD5547/AD5557 are available in a compact TSSOP-38
package and operate at the extended automotive temperature
range of –40°C to +125°C.
