The AD5512A /AD5542Aare single, 12-/16-bit, serial input, unbuffered voltage output digital-to-analog converters (DAC) that operate from a single 2.7 V to 5.5 V supply. The DAC output range extends from 0 V to VREFand is guaranteed monotonic, providing 1 LSB INL accuracy at 16 bits without adjustment over the full specified temperature range of −40°C to +85°C (AD5542A) or −40°C to +125°C (AD5512A).Offering unbuffered outputs, the AD5512A / AD5542A achieve a 1 μs settling time with low offset errors ideal for high speed open loop control.The AD5512A / AD5542A incorporate a bipolar mode of operation that generates a ±VREFoutput swing. The AD5512A / AD5542A also include Kelvin sense connections for the reference and analog ground pins to reduce layout sensitivity.The AD5512A / AD5542A are available in a 16-lead LFCSP with the AD5542A also available in a 10-lead LFCSP and a 16-lead TSSOP. The AD5512A / AD5542A use a versatile 3-wire interface that is compatible with 50 MHz SPI, QSPI™, MICROWIRE™, and DSP interface standards.APPLICATIONSAutomatic test equipmentPrecision Source-measure InstrumentsData Acquisition SystemsMedical and aerospace InstrumentationCommunications equipmentPRODUCT HIGHLIGHTS16-bit performance without adjustment.2.7 V to 5.5 V single supply operation.Low 11.8 nV/√Hznoise spectral density.Low 0.05 ppm/°C temperature drift.3 mm × 3 mm LFCSP and TSSOP packaging.
