Description

The LTC®2602/LTC2612/LTC2622 are dual 16-,14- and 12-bit, 2.5V-to-5.5V rail-to-rail voltage-output DACs, in a tiny 8-lead MSOP package. 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.

The LTC2602/LTC2612/LTC2622 incorporate a poweron reset circuit. During power-up, the voltage outputs rise less than 10mV above zero scale, and after powerup, they stay at zero scale until a valid write and update take place.
