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 external buffer.
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.Applications
