LTC1821 - 16-Bit, Ultra Precise, Fast Settling VOUT DAC

The device includes an internal deglitcher circuit that reduces the glitch impulse to less than 2nV•s (typ). The LTC1821 settles to 1LBS in 2µs with a full-scale 10V step. The combination of fast, precise settling and ultra low glitch make the LTC1821 ideal for precision industrial control applications.

The asynchronous CLR pin resets the LTC1821 to zero scale and resets the LTC1821-1 to midscale.
