Analog Devices AD5691, AD5692, & AD5693 nanoDAC+®
ADI AD5691, AD5692, & AD5693 nanoDAC+® digital to analog converters are low power, single-channel, 16-/14-/12-bit buffered voltage output DACs. The devices include an enabled by default internal 2.5V reference, offering 2ppm/°C drift. The output span can be programmed to be 0V to VREF or 0V to 2×VREF. All devices operate from a single 2.7V to 5.5V supply and are guaranteed monotonic by design. The devices are available in a 2mm × 2mm, 8-lead LFCSP or a 10-lead MSOP. The internal power-on reset circuit ensures that the DAC register is written to zero scale at power-up while the internal output buffer is configured in normal mode. The AD5693R/AD5692R/AD5691R contain a power-down mode that reduces the current consumption of the device to 2μA (maximum) at 5V and provides software selectable output loads. The AD5693R/AD5692R/AD5691R use an I2C interface. Some device options also include an asynchronous RESET pin and a VLOGIC pin, allowing 1.8V compatibility.
