They have built-in high performance output buffers and are guaranteed monotonic. These parts establish new board-density benchmarks for 16- and 14-bit DACs and advance performance standards for output drive, crosstalk and load regulation in single-supply, voltage-output multiples. The parts use a simple SPI/MICROWIRE patible 3-wire serial interface which can be operated at clock rates up to 50MHz. Daisychain capability and a hardware CLR function are included. The LTC2600/LTC2610/LTC2620 incorporate a power-on reset circuit. During power-up, the voltage outputs rise less than 10m V above zero-scale; and after power-up, they stay at zero-scale until a valid write and update take place.
