General Description
The MAX5547 dual, 10-bit, dual range, digital-to-analog
converter (DAC) sinks up to 3.6mA of current, making it
ideal for laser-driver-control applications. Parallel the
MAX5547 outputs to sink higher current (up to 7.2mA
max). Operating from a single +2.7V to +5.25V
supply, the MAX5547 typically consumes 1mA
(internal reference).
The MAX5547 operates from a precision +2.5V internal
4ppm/°C reference or an external reference in the
+2.45V to +2.55V range. The maximum full-scale cur-
rent-sink range is software programmable to 3.6mA or
1.2mA for each DAC. A 10MHz SPI-compatible serial
interface 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.
