Product Details
The AD5676 is a low power, octal, 16-bit buffered voltage output digital-to-analog converter (DAC). The device includes a gain select pin, giving a full-scale output of VREF (gain = 1) or 2 × VREF (gain = 2). The AD5676 DAC operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. The AD5676 is available in 20-lead TSSOP and LFCSP packages.
The internal power-on reset circuit and the RSTSEL pin of the AD5676 ensure that the output DACs power up to zero scale or midscale and then remain there until a valid write takes place. The AD5676 contains a per channel power-down mode that typically reduces the current consumption of the device to 1 µA.
The AD5676 employs a versatile serial peripheral interface (SPI) that operates at clock rates up to 50 MHz, and contains a VLOGIC pin intended for 1.62 V to 5.5 V logic.

Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
