GENERAL DESCRIPTION

The AD5547-EP is a dual precision, 16-bit, multiplying, low power,

current-output, parallel input, digital-to-analog converter (DAC). It

is designed to operate from a single +5 V supply with ±10 V

multiplying references for 4-quadrant outputs with a 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,

an external buffer.

The AD5547-EP is available in a compact, 38-lead TSSOP

package and operates at the extended automotive temperature

range of −55°C to +125°C. Additional application and technical

information can be found in the AD5547 data sheet.
