HS3140/SP7514
14-Bit Multiplying DACs
DESCRIPTION…
The SP7514 and HS3140 are precision 14-bit multiplying DACs, that provide four-quadrant
multiplication. Both parts accept both AC and DC reference voltages. The SP7514 is available
for use in commercial and industrial temperature ranges, packaged in a 20-pin SOIC. The
HS3140 is available in commercial and military temperature ranges, packaged in a 20-pin
side-brazed DIP.
