ADI LTC2631ITS8-LZ12#TRMPBF

The LTC2631 is a family of 12-, 10-, and 8-bit voltage-output DACs with an integrated, high accuracy, low-drift reference in an 8-lead TSOT-23 package. It has a rail-to-rail output buffer that is guaranteed monotonic. The LTC2631-L has a full-scale output of 2.5V, and operates from a single 2.7V to 5.5V supply. The LTC2631-H has a full-scale output of 4.096V, and operates from a 4.5V to 5.5V supply. A 10ppm/°C reference output is available at the REF pin. Each DAC can also operate in External Reference mode, in which a voltage supplied to the REF pin sets the full-scale output. The LTC2631 DACs use a 2-wire, I²C-compatible serial interface. The LTC2631 operates in both the standard mode (clock rate of 100kHz) and the fast mode (clock rate of 400kHz). The LTC2631 incorporates a power-on reset circuit. Options are available for reset to zero-scale or reset to mid-scale after power-up.
