AD5675ARUZ

AD5675ARUZ is a low-power, octal, 16bit buffered voltage output digital-to-analogue converter (DAC). This device includes a gain select pin, giving a full-scale output of VREF (gain = 1) or 2 × VREF (gain = 2). This device operates from a single 2.7V to 5.5V supply and is guaranteed monotonic by design. The power-on reset circuit and an RSTSEL pin ensure that the output DACs power up to zero scale or midscale and remain there until a valid write takes place. It contains a power-down mode, reducing the current consumption to 1µA typical while in power-down mode. It uses a versatile 2-wire serial interface that operates at clock rates up to 400KHz and includes a VLOGIC pin intended for 1.62V to 5.5V logic. It is used in applications such as optical transceivers, base station power amplifiers, process control (PLC input/output cards), industrial automation, and data acquisition systems.
