LTC2629CGN-1#TRPBF

LTC2629CGN-1#TRPBF is a quad 12bit, 2.7V to 5.5V rail-to-rail voltage output DAC. It has a built-in high performance output buffers and are guaranteed monotonic. The parts use a 2-wire, I²C compatible serial interface. The LTC2629 operate in both the standard mode (clock rate of 100KHz) and the fast mode (clock rate of 400KHz. The LTC2629 incorporate a power-on reset circuit. During power-up, the voltage outputs rise less than 10mV above zero-scale; after power-up, they stay at zero-scale until a valid write and update take place. The power-on reset circuit resets the LTC2609-1 to mid-scale. The voltage outputs stay at midscale until a valid write and update take place. Applications include mobile communications, process control and industrial automation, automatic test equipment and instrumentation.
