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 and load regulation in single-supply, voltage-output DACs. The parts use a 2-wire, I2C patible serial interface. The LTC2607/LTC2617/LTC2627 operate in both the standard mode (clock rate of 100k Hz) and the fast mode (clock rate of 400k Hz). An asynchronous DAC update pin (LDAC) is also included. The LTC2607/LTC2617/LTC2627 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 LTC2607-1/LTC2617-1/ LTC2627-1 to mid-scale. The voltage outputs stay at midscale until a valid write and update takes place.
