... The parts use a simple SPI/MICROWIRE™ compatible 3-wire serial interface which can be operated at clock rates up to 50MHz. The LTC2602/LTC2612/LTC2622 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 LTC2602/ LTC2612/LTC2622 contain circuitry to reduce the power- on glitch; furthermore, the glitch amplitude can be made smaller by reducing the ramp rate of the power supply. For ...

... Resistance here will add directly to the effective DC output impedance of the device (typically 0.050 ), and will degrade DC crosstalk. Note that the LTC2602/LTC2612/LTC2622 are no more susceptible to these effects than other parts of their type; on the contrary, they allow layout-based performance improvements to shine rather than limiting attainable performance with excessive internal resistance ...
