Digitally controlled calibration

Digital waveform generation

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 (R_FB) simplifies the I-V conversion with an

external buffer.

GENERAꢀ DESCRIPTION

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 1ꢀ V multiplying references for 4-quadrant

outputs with up to 4 MHz bandwidth.

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

package and operate at the extended automotive temperature

range of –4ꢀ°C to +125°C.
