AD5697RBRUZ-RL7

AD5697RBRUZ-RL7 is a low power, dual, 12bit buffered voltage output, nanoDAC® digital-to-analogue converter (DAC). It incorporates a power-on reset circuit and an RSTSEL pin that ensures that the DAC outputs power upto zero scale or midscale and remains there until a valid write takes place. It contains a per-channel power-down feature that reduces the current consumption of the device to 4µA at 3V 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 1.8V/3V/5V logic. It is used in applications such as base station power amplifiers, process controls (programmable logic controller [PLC] I/O cards), industrial automation, and data acquisition systems.
