The MAX5832 is a 14-bit, 9-channel, current-output digital-to-analog converter (DAC). The device operates from a low +3.0V power supply and provides 14-bit performance without any adjustment.

The device’s output ranges are optimized to bias a high-power tunable laser source. Each of the 9 channels provides a current source. Channels 1 and 2 provide 10mA current. An internal multiplexer switches the outputs of each channel to one of four external nodes. Channel 3 provides a selectable current of 2mA or 20mA. Channel 4 provides 90mA. Channel 5 provides 180mA. Channel 6 provides a selectable current of -60mA or +300mA. Channel 7 provides 90mA. Channels 8 and 9 provide a selectable current of 15mA or 35mA. Connect DAC outputs in parallel to obtain additional current or to achieve higher resolution. The device contains an internal reference.

An I²C-compatible interface drives the device with clock rates of up to 400kHz. An active-high asynchronous CLR input resets DAC codes to zero independent of the serial interface. The device provides a separate power-supply input for driving the interface logic.

The MAX5832 is specified over the -40°C to +105°C temperature range, and is available in a 3mm x 3mm, 36-bump WLP.
