AD5676ARUZ

AD5676 is an octal, 16bit nanoDAC+ with SPI interface. It is a low power, octal, 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 DAC operates from a single 2.7V to 5.5V supply and is guaranteed monotonic by design. 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. It 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. Application includes optical transceivers, base station power amplifiers, process control (PLC input/output cards), industrial automation, data acquisition systems.
