    The AD5705R/AD5706R are 4-channel, 16-bit resolution, low-noise, programmable current-output digital-to-analog converters (DACs). These devices are ideal for applications such as photonic control and current-mode bias supply.
    This device features a 2.5V voltage reference, load DAC, A/B toggle, and dithering capabilities. A built-in multiplexer allows monitoring of POWER SUPPLIES voltage, output voltage, output current, and internal die temperature.

    The AD5705R/AD5706R supports multiple programmable output current ranges (up to 300mA). Addressable pins allow up to four devices to communicate by sharing a single SPI bus.
    Each DAC channel operates independently on a positive POWER SUPPLIES rail (PVDDx) ranging from 1.65V to 3.6V, optimizing both power efficiency and thermal performance. The device requires a 2.9V to 3.6V AVDD POWER SUPPLIES and is rated to operate over a wide temperature range of -40°C to +125°C.
