ADI LTC2635CMSE-HZ10#TRPBF

The LTC2635 is a family of quad 12-, 10-, and 8-bit voltage-output DACs with an integrated, high-accuracy, low-drift reference in a 16-pin QFN or a 10-lead MSOP package. It has rail-to-rail output buffers and is guaranteed monotonic. The LTC2635-L has a full-scale output of 2.5Vi, and operates from a single 2.7V to 5.5V supply. The LTC2635-H has a full-scale output of 4.096V, and operates from a 4.5V to 5.5V supply. Each DAC can also operate with an external reference, which sets the fullscale output to the external reference voltage. These DACs communicate via a 2-wire I2C-compatible serial interface. The LTC2635 operates in both the standard mode (clock rate of 100kHz) and the fast mode (clock rate of 400kHz). The LTC2635 incorporates a power-on reset circuit. Options are available for reset to zero-scale, reset to mid-scale in internal reference mode, reset to mid-scale in external reference mode, or reset with all DAC outputs in a high-impedance state after power-up.
