... Daisy-chain capability and a hardware CLR function are included. The LTC2604/LTC2614/LTC2624 incorporate a power- on reset circuit. During power-up, the voltage outputs rise less than 10mV above zero scale; and after power- up, they stay at zero scale until a valid write and update take place ...

... For some applications, downstream circuits are active during DAC power-up, and may be sensitive to nonzero outputs from the DAC during this time. The LTC2604/ LTC2614/LTC2624 contain circuitry to reduce the power- on glitch; furthermore, the glitch amplitude can be made arbitrarily small by reducing the ramp rate of the power supply ...
