DESCRIPTION…
The SP7512 and HS3120 are precision 12-bit multiplying DACs, double–buffered for easy
interfacing with microprocessor busses. Both unipolar and bipolar operation can be accommo-
dated with a minimum of external components. The SP7512 is available for use in commercial
and industrial temperature ranges, packaged in a 28-pin SOIC. The HS3120 is available in
commercial and military temperature ranges, packaged in a 28–pin side–brazed DIP.
