... These DACs include an internal deglitcher circuit that reduces the glitch impulse to less than 2nV-s (typ). The asynchronous CLR pin resets the LTC1591/LTC1597 to zero scale and LTC1591-1/LTC1597-1 to midscale. The LTC1591/LTC1597 are available in 28-pin SSOP and PDIP packages and are specified over the industrial tempera- ture range ...

Unipolar Mode (2-Quadrant Multiplying, V The LTC1591/LTC1597 can be used with a single op amp to provide 2-quadrant multiplying operation as shown in Figure 1. With a fixed – 10V reference, the circuits shown give a precision unipolar 0V to 10V output swing. ...
