GENERAL DESCRIPTION
The AD5689R/AD5687R members of the nanoDAC+™ family are low power, dual, 16-/12-bit buffered voltage output digital-to-analog converters (DACs). The devices include a 2.5 V, 2 ppm/°C internal reference (enabled by default) and a gain select pin giving a full-scale output of 2.5 V (gain = 1) or 5 V (gain = 2). The devices operate from a single 2.7 V to 5.5 V supply, are guaranteed monotonic by design, and exhibit less than 0.1% FSR gain error and 1.5 mV offset error performance. Both devices are available in a 3 mm × 3 mm LFCSP and a TSSOP package.

FEATURES

    Low drift 2.5 V reference: 2 ppm/°C typical
    Tiny package: 3 mm × 3 mm, 16-lead LFCSP
    TUE: ±0.1% of FSR maximum
    Offset error: ±1.5 mV maximum
    Gain error: ±0.1% of FSR maximum
    High drive capability: 20 mA, 0.5 V from supply rails
    User-selectable gain of 1 or 2 (GAIN pin)

    1.8 V logic compatibility
    50 MHz SPI with readback or daisy chain
    Low glitch: 0.5 nV-sec
    Low power: 3.3 mW at 3 V
    2.7 V to 5.5 V power supply
    −40°C to +105°C temperature range
