GENERAL DESCRIPTION

The AD5547/AD5557 are dual precision, 16-/14-bit, multiplying,

low power, current-output, parallel input, digital-to-analog

converters (DACs). They are designed to operate from single

+5 V supply with ±10 V multiplying references for 4-quadrant

outputs with 6.8 MHz bandwidth.

The built-in, 4-quadrant resistors facilitate resistance matching

and temperature tracking, which minimize the number of

components needed for multiquadrant applications. In addition,

the feedback resistor (R

) simplifies the I-to-V conversion with

an external buffer.

The AD5547/AD5557 are available in a compact, 38-lead TSSOP

package and operate at the extended automotive temperature

range of −40°C to +125°C.
