The LTC2602CMS8#PBF is a dual 16-Bit rail-to-rail D/A Converter that 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 single-supply, 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. The LTC2602 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 zero scale until a valid write and update take place. For some applications, downstream circuits are active during DAC power-up and may be sensitive to nonzero outputs from the DAC during this time. For power-constrained applications, power-down mode can be used to reduce the supply current whenever less than two outputs are needed.
