The LTC2631 family of pin- and software-compatible 12-, 10-, and 8-bit D/A converters are housed in a TSOT-23 package — making it the smallest I2 C DAC family with an internal reference on the market today. The LTC2631 makes the integrated 10 ppm/°C reference output available to drive the reference inputs for all other data converters on the board, while maintaining good stability over temperature.
The LTC2631 releases alongside an SPI-equivalent LTC2640 12-,10-,8-bit family, each offering the choice of a 2.5 or 4.096 V full-scale output range. Alternatively, an external reference can be applied if more accuracy or a non-standard voltage range is required. The DACs draw only 180 μA of supply current at 3 V.
