Description

The AD5671R/AD5675R are low power, octal, 12-/16-bit buffered voltage output digital-to-analog converters (DACs). They 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 and are guaranteed monotonic by design. The AD5671R/AD5675R are available in a 20-lead TSSOP and in a 20-lead LFCSP and incorporate a power-on reset circuit and a RSTSEL pin that ensures the DAC outputs power up to zero scale or midscale and remain there until a valid write. The AD5671R/AD5675R contain a power-down mode, reducing the current consumption to 1 μA typical while in power-down mode.Product HighlightsHigh Relative Accuracy (INL).AD5671R (12-bit): ±1 LSB maximumAD5675R (16-bit): ±3 LSB maximumLow Drift 2.5 V On-Chip ReferenceApplicationsOptical transceiversBase-station power amplifiersProcess control (PLC input/output cards)Industrial automationData acquisition systems
