They have built-in high performance output buffers and are guaranteed monotonic. These parts establish new board-density benchmarks for 16-/14-bit DACs and advance performance standards for output drive, crosstalk and load regulation in single supply, voltage-output multiples. The parts use the 2-wire I2C patible serial interface. The LTC2605/LTC2615/LTC2625 operate in both the standard mode (maximum clock rate of 100k Hz) and the fast mode (maximum clock rate of 400k Hz). The LTC2605/LTC2615/LTC2625 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. The power-on reset circuit resets the LTC2605-1/LTC2615-1/ LTC2625-1 to mid-scale. The voltage output stays at midscale until a valid write and update takes place.
