The LTC2606/LTC2616/LTC2626 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. The power-on reset circuit resets the LTC2606-1/LTC2616-1/ LTC2626-1 to midscale. The voltage outputs stay at midscale until a valid write and update take place. , LTC and LT are registered trademarks of Linear Technology Corporation.
