The LMS12 is a high-speed 12 x 12-bit combinatorial multiplier integrated with a 26-bit adder in a single 84-pin package. It is an ideal building block for the implementation of very highspeed FIR filters for video, RADAR, and other similar applications. The LMS12 implements the general form (A•B) + C. As a result, it is also useful in implementing polynomial approximations to transcendental functions.
