The MAX5547 dual, 10-bit, dual range, digital-to-analogconverter (DAC) sinks up to 3.6mA of current, making itideal for laser-driver-control applications. Parallel theMAX5547 outputs to sink higher current (up to 7.2mAmax). Operating from a single +2.7V to +5.25Vsupply, the MAX5547 typically consumes 1mA(internal reference).The MAX5547 operates from a precision +2.5V internal4ppm/°C reference or an external reference in the+2.45V to +2.55V range. The maximum full-scale current-sink range is software programmable to 3.6mA or1.2mA for each DAC. A 10MHz SPI™-compatible serialinterface configures the device.The MAX5547 is available in a 3mm x 3mm x 0.8mm 8-pin TDFN package and is specified over the -40°C to+85°C extended temperature range.ApplicationsLaser-Driver ControlPin-Diode Bias CurrentsModulation CurrentsAverage PowerExtinction Ratios
