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. Table 1.
