AD5546/AD5556 Simplified Block Diagram 2 mA full-scale current 20%, with V = 10 V REF Automotive operating temperature: 40C to +125C GENERAL DESCRIPTION Compact TSSOP-28 package The AD5546/AD5556 are precision 16-/14-bit, multiplying, low power, current output, parallel input digital-to-analog converters APPLICATIONS (DACs). They operate from a single 2.7 V to 5.5 V supply with Automatic test equipment 10 V multiplying references for four-quadrant outputs. Built- Instrumentation in four-quadrant resistors facilitate the resistance matching and Digitally controlled calibration temperature tracking that minimize the number of components Digital waveform generation needed for multiquadrant applications. The feedback resistor (R ) simplifies the I-V conversion with an external buffer. The FB AD5546/AD5556 are packaged in compact TSSOP-28 packages with operating temperatures from 40C to +125C. The EVAL-AD5546SDZ is available for evaluating DAC perfor- mance.
