... DACs and advance performance standards for output drive and load regulation in single-supply, voltage-output DACs. The parts use a 2-wire, I LTC2609/LTC2619/LTC2629 operate in both the standard mode (clock rate of 100kHz) and the fast mode (clock rate of 400kHz). The LTC2609/LTC2619/LTC2629 incorporate a power-on reset circuit. During power-up, the voltage outputs rise less than 10mV above zero scale ...
