LTC2635HMSE-LMI12#PBF

LTC2635HMSE-LMI12#PBF is a quad-channel, 12bit voltage-output DAC with an integrated, high-accuracy, low-drift reference. LTC2635-L has rail-to-rail output buffers and is guaranteed monotonic. LTC2635-L has a full-scale output of 2.5V and operates from a single 2.7V to 5.5V supply. This DAC communicates via a 2-wire I²C-compatible serial interface. It operates in both the standard mode (clock rate of 100KHz) and the fast mode (clock rate of 400KHz). It incorporates a power-on reset circuit. Applications include mobile communications, process control and industrial automation, power supply margining, portable equipment, and automotive.
