On-chip precision output amplifiers allow rail-to-rail swing over the supply range of2.7V to 5.5V. A per channel power-down feature, accessed over the serial interface, reducescurrent consumption to 200µA per channel at 5V. Single, dual and quad versions are available.The DAC8560 is a 16-bit, single-channel, DAC with an internal 2ppm/°C reference.DAC8554AVDDIOVDDDataBuffer ADACRegister AVREFHDAC AVOUTAVOUTVOUTApplications• Portable instrumentation• Closed-loop servo control• Process control• Data acquisition systems• Programmable attenuation• PC peripheralsSYNCSCLKDIN1B24-BitSerialParallel ShiftRegisterBDataBuffer DBufferControlDACRegister DRegisterControlDAC DA0 A1 LDAC ENABLE VREFLPower DownControl LogicResistorNetworkVOUTDAC8554 functional block diagram.Highest Accuracy and Industrial Bipolar DACsDAC88xx and DAC78xx Multiplying FamilyGet samples, datasheets and evaluation modules at: www.ti.com/sc/device/PARTnumber (Replace PARTnumber with DAC8801, DAC8802, DAC8803, DAC8805,DAC8806, DAC8811, DAC8812, DAC8814, DAC8820, DAC8822, DAC7811, DAC7821 or DAC7822)Key Features• Relative accuracy: 1LSB (max)• ±2mA full-scale current with V REF = ±10V• Settling time: 0.5µs• Midscale or zero-scale reset• Four separate 4-quadrant (±10V) multiplyingreference inputs (DAC8814)• Reference bandwidth: 10MHz• Reference dynamics: –105dB THD• Double-buffered input registers• Internal power-on reset• Packaging: MSOP-8, SON-8, SSOP-28,TSSOP-16Applications• Automatic test equipment• Instrumentation• Digitally controlled calibration• Industrial control PLCsThe DAC88xx and DAC78xx families of current output DACs are designed to operate from asingle +2.7V to 5V supply and are available in single, dual and quad versions.
