MAX5547

www.DataSheet4U.com 19-3988; Rev 0; 2/06 Dual, 10-Bit, Current-Sink Output DAC 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 current-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 8pin TDFN package and is specified over the -40°C to +85°C extended temperature range. ♦ Dual Current-Sink DACs ♦ 10-Bit Resolution ♦ Two Software-Programmable Full-Scale Current Ranges: 3.6mA or 1.2mA ♦ Parallelable Outputs for Up to 7.2mA (max) ♦ +2.5V Internal Reference Drifts Only 4ppm/°C ♦ +2.7V to +5.25V Single-Supply Operation ♦ INL: ±4 LSB (1.2mA Output) ♦ DNL: ±0.75 LSB (Guaranteed Monotonic) ♦ Low +0.8V Output Compliance ♦ Ultra-Small, 3mm x 3mm x 0.8mm, 8-Pin TDFN Package Features MAX5547 Applications Laser-Driver Control Pin-Diode Bias Currents Modulation Currents Average Power Extinction Ratios PART Ordering Information TEMP RANGE PINPACKAGE TOP MARK APF PKG CODE T833-2 MAX5547ETA -40°C to +85°C 8 TDFN...
