... LD pin. An asynchronous clear input (CLR) resets the LTC1596 to zero scale (and the LTC1596-1 to midscale) when pulled low (see Truth Table 2). The LTC1596 also has a data output pin SRO that can be connected to the SRI input of another DAC to daisy-chain multiple DACs on one 3-wire interface (see LTC1596 Timing Diagram) ...

... V ) OUT REF REF The LTC1595/LTC1596 can be used with a dual op amp and three external resistors to provide 4-quadrant multi- plying operation as shown in Figure 2 (last page). With a fixed 10V reference, the circuits shown give a precision bipolar –10V to 10V output swing. Using the LTC1596-1 will cause the power-on reset and clear pin to reset the DAC to midscale (bipolar zero) ...
