LTC2635 Datasheet | Linear Technology

LTC2635 Quad 12-/10-/8-Bit I2C VOUT DACs with 10ppm/°C Reference Features n DESCRIPTION The LTC®2635 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 2.5V, 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 municate via a 2-wire I2C-patible serial interface. The LTC2635 operates in both the standard mode (clock rate of 100k Hz) and the fast mode (clock rate of 400k Hz). 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.
