LTC2611 - 14-Bit Rail-to-Rail DACs in 10-Lead DFN

These parts establish new board-density benchmarks for 16- and 14-bit DACs and advance performance standards for output drive and load regulation in single-supply, voltage-output DACs.

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, hardware CLR and asynchronous DAC update (LDAC) pins are included.

The LTC2601/LTC2611/LTC2621 incorporate a power-on reset circuit. During power-up, the voltage outputs rise less than 10mV above zero scale until a valid write and update take place. The power-on reset circuit resets the LTC2601-1/LTC2611-1/LTC2621-1 to midscale. The voltage outputs stay at midscale until a valid write and update take place.
