DESCRIPTION

The LMA1009 and LMA2009 are highspeed, low power 12-bit multiplier-accumulators. They are pin-for-pin equivalent to the TRW TDC1009/TMC2009 multiplier-accumulators. The LMA1009 and LMA2009 are functionally identical; they differ only in packaging. Full ambient temperature range operation is achieved by the use of advanced CMOS technology.
