Description

The AD5694R is a low power, quad, 16-bit buffered voltage output DAC. The device includes 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 device operates from a single 2.7 V to 5.5 V supply, is guaranteed monotonic by design, and exhibits less than 0.1% FSR gain error and 1.5 mV offset error performance. The device is available in a 3 mm × 3 mm LFCSP and a TSSOP package.The AD5694R also incorporates a power-on reset circuit and a RSTSEL pin that ensures that the DAC outputs power up to zero scale or midscale and remain there until a valid write takes place. Each part contains a per-channel power-down feature that reduces the current consumption of the device to 4 μA at 3 V while in power-down mode.The AD5694R uses a versatile 2-wire serial interface that operates at clock rates up to 400 kHz, and includes a VLOGICpin intended for 1.8 V/3 V/5 V logic.Product HighlightsHigh Relative Accuracy (INL).AD5696R (16-bit): ±2 LSB maximum.AD5695R (14-bit): ±1 LSB maximum.AD5694R (12-bit): ±1 LSB maximum.Low Drift 2.5 V On-Chip Reference.2 ppm/°C typical temperature coefficient.5 ppm/°C maximum temperature coefficient.Two Package Options.3 mm × 3 mm, 16-lead LFCSP.16-lead TSSOP.ApplicationsOptical transceiversBase-station power amplifiersProcess control (PLC I/O cards)Industrial automationData acquisition systems
