AD5676BRUZ-REEL7

AD5676 is a low power, octal, 16bit buffered voltage output digital-to-analogue converter (DAC). The device includes a gain select pin, giving a full-scale output of VREF (gain = 1) or 2 × VREF (gain = 2). The internal power-on reset circuit and the RSTSEL pin of this ensure that the output DACs power up to zero scale or midscale and then remain there until a valid write takes place. This contains a per channel power-down mode that typically reduces the current consumption of the device to 1µA. This employs a versatile serial peripheral interface (SPI) that operates at clock rates up to 50MHz, and contains a VLOGIC pin intended for 1.62V to 5.5V logic. Typical applications are optical transceivers, base station power amplifiers, process control (PLC input/output cards), industrial automation, data acquisition systems.
