These parts have separate reference inputs for each DAC. They have built-in high performance output buffers and are guaranteed monotonic. These parts establish advanced performance standards for output drive, crosstalk and load regulation in singlesupply, voltage output multiples. The parts use a simple SPI/MICROWIRE compatible 3-wire serial interface which can be operated at clock rates up to 50MHz. Daisy-chain capability and a hardware CLR function are included. The LTC2604/LTC2614/LTC2624 incorporate a power-on reset circuit. During power-up, the voltage outputs rise less than 10mV above zero scale; and after power-up, they stay at...
