AD5676 Octal, 16-Bit nanoDAC+ with SPI Interface

High Relative Accuracy (INL): AD5676 (16-bit): ±3 LSB maximum −40°C to +125°C temperature range 20-lead, TSSOP RoHS-Compliant Package

The AD5676 is a low power, octal, 16-bit buffered voltage output digital-to-analog converter (DAC). It includes a gain select pin giving a full-scale output of 2.5 V (gain = 1) or 5 V (gain = 2). All devices operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design. The AD5676 is available in a 20-lead TSSOP.

The AD5676 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 device contains a per channel power-down feature that reduces the current consumption of the device to 2.5 µA while in power-down mode.

The AD5676 employs a versatile serial peripheral interface (SPI) 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.
