Maxim Integrated Products introduces the MAX5547, a 10-bit, SPI, dual, current-sink DAC that integrates a precision 4ppm/C bandgap reference, operates from a single 2.7V to 5.25V supply, and fits in a 3-by-3mm, 8-pin TDFN package.

According to the press release, the MAX5547 is highly accurate (4LSB at 1.2mA), and guaranteed monotonic over the extended operating temperature range of -40C to 85C. Maxim added that the current-sink operation of its new DAC makes it ideal for laser-driver control applications. The MAX5547 settles to within 1LSB of full scale in 10?s (typ). The full-scale output sink-current range is software selectable from 0 to 1.2mA or 0 to 3.6mA, and is independent for each DAC.

Pricing for the MAX5547 starts at $3.19 (1,000-up, FOB USA).
