Description

The AD5673R/AD5677R 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 AD5673R/AD5677R 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 remain at zero scale or midscale until a valid write. The AD5673R/AD5677R contain a power-down mode that reduces the current consumption to 2 µA typical.ApplicationsOptical transceiversBase station power amplifiersProcess control (programmable logic controller (PLC) input/output cards)Industrial automationData acquisition systemsProduct HighlightsHigh channel density: 16 channels in 4 mm × 4 mm LFCSP.High relative accuracy (INL).AD5673R (12-bit): ±1 LSB maximum.AD5677R (16-bit): ±4 LSB maximum.Low drift, 2.5 V, on-chip reference.
