Analog Devices EVAL-AD5687RSDZ

Evaluation Board For 12-Bit Digital-to-Analog Converter

EVALUATION MODULE, DATA CONVERTER

SPI INTERFACE EVALUATION BOARD

The AD5687R nanoDAC+™ is a dual, 12-bit, rail-to-rail, voltage output DACs. 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 AD5687R 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 remains 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 AD5689R employs a versatile SPI interface that operates at clock rates up to 50 MHz, and all devices contain a VLOGIC pin intended for 1.8 V/3 V/5 V logic supplies.
