Description

The AD5672R/AD5676Rare 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 AD5672R/AD5676R 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 that the DAC outputs power up to zero scale or midscale and remains there until a valid write. The AD5672R/AD5676R contain a power-down mode, reducing the current consumption to 1 µA typical while in power-down mode. The AD5676R is also available in a 16-ball WLCSP.PRODUCT HIGHLIGHTSHigh Relative Accuracy (INL).AD5672R (12-bit): ±1 LSB maximumAD5676R (16-bit): ±3 LSB maximumLow Drift 2.5 V On-Chip Reference.High Channel Density.Eight channels in 2.5 mm × 2.4 mm WLCSP (AD5676R).APPLICATIONSOptical transceiversBase-station power amplifiersProcess control (PLC input/output cards)Industrial automationData acquisition systems
