Part details & applications

The AD5706R is a 4-channel, 16-bit resolution, low noise programmable current output, digital-to-analog converter (DAC). The device is ideal for applications such as photonics control and current-mode biasing.

The device features an integrated 2.5V voltage reference, along with load DAC, A/B toggle, and dither functions. An onboard multiplexer allows for monitoring of supply and output voltages, output currents, and the internal die temperature.

The AD5706R supports several programmable output current ranges, with a maximum of 300mA. With addressable pins, up to four devices can share a single SPI bus for communication.

Each DAC channel operates independently with its own positive power supply rail (PVDDx) that can range from 1.65V to 3.6V, optimizing both power efficiency and thermal performance. The device requires a 2.9V to 3.6V AVDD supply and is rated for operation across a wide temperature range from −40°C to +125°C.

APPLICATIONS

Photonics control
Optical communications
LED driver programmable current source
Current-mode biasing
