LMA2010JC35 16 x 16-bit Multiplier-Accumulator

TC, ACC, and SUB controls are latched on the rising edge of the logical OR of CLK A and CLK B. TC specifies the input as two’s complement (TC HIGH) or unsigned magnitude (TC LOW). RND, when HIGH, adds ‘1’ to the most significant bit position of the least significant half of the product. Subsequent truncation of the 16 least The LMA1010 and LMA2010 produce si.
