Product Details
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.
