LTC2632CTS8-HZ12#TRMPBF

LTC2632CTS8-HZ12#TRMPBF is a dual-channel, 12bit voltage-output DAC with an integrated, high-accuracy, low-drift reference. LTC2632-H has rail-to-rail output buffers and is guaranteed monotonic. LTC2632-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 full-scale output to the external reference voltage. These DACs communicate via a simple SPI/MICROWIRE compatible 3-wire serial interface which operates at clock rates up to 50MHz. It incorporates a power-on reset circuit. Applications include mobile communications, process control and industrial automation, automatic test equipment, portable equipment, and automotive.
