AD5546/AD5556 Simplified Block Diagram GENERAL DESCRIPTION The AD5546/AD5556 are precision 16-/14-bit, multiplying, low power, current output, parallel input digital-to-analog converters (DACs). They operate from a single 2.7 V to 5.5 V supply with ±10 V multiplying references for four-quadrant outputs. Builtin four-quadrant resistors facilitate the resistance matching and temperature tracking that minimize the number of ponents needed for multiquadrant applications. The feedback resistor (RFB) simplifies the I-V conversion with an external buffer. The AD5546/AD5556 are packaged in pact TSSOP-28 packages with operating temperatures from - 40°C to +125°C. The EVAL-AD5546SDZ is available for evaluating DAC performance. For more information, see the UG-309 evaluation board user guide. +10V + U2A OP2177 -...
