High performance High relative accuracy (INL): ±1 LSB maximum at 12 bits TUE: ±0.14% of FSR maximum Offset error: ±1.5 mV maximum Gain error: ±0.06% of FSR maximum Low drift, 2.5 V voltage reference temperature coefficient: 2 ppm/°C typical 40 mA short-circuit current Wide operating ranges −40°C to +125°C temperature range 2.7 V to 5.5 V power supply range Simplified implementation User selectable gain of 1 or 2 (GAIN pin) 1.8 V logic compatibility 50 MHz serial peripheral interface (SPI) with readback or daisy chain 28-lead, 4 mm × 4 mm, RoHS compliant LFCSP The AD5674/AD5674R/AD5679/AD5679R are low power, 16-channel, 12-/16-bit, buffered voltage output, digital-to-analog converters (DACs) that include a 2.5 V, 2 ppm/°C internal reference (enabled by default), and a gain select pin, resulting in 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 range and are guaranteed monotonic by design. The AD5674/AD5674R/AD5679/AD5679R are available in a 28-lead lead frame chip scale package (LFCSP) and incorporate a power-on reset (POR) circuit that ensures that the DAC outputs power up to and remains at zero-scale or midscale until a valid write. The AD5674/AD5674R/AD5679/AD5679R contain a power-down mode that reduces the current consumption to 2 μA typical. High channel density: 16 channels in 4 mm × 4 mm LFCSP. High relative accuracy (integral nonlinearity (INL)) ±4 LSB maximum. Low drift, 2.5 V, on-chip reference.
