The LM98714 is a fully integrated, high performance 16-Bit, 45 MSPS signal processing solution for digital color copiers, scanners, and other image processing applications. High-speed signal throughput is achieved with an innovative architecture utilizing Correlated Double Sampling (CDS), typically employed with CCD arrays, or Sample and Hold (S/H) inputs (for Contact Image Sensors and CMOS image sensors). The signal paths utilize 8 bit Programmable Gain Amplifiers (PGA), a ±9-Bit offset correction DAC and independently controlled Digital Black Level correction loops for each input. The PGA and offset DAC are programmed independently allowing unique values of gain and offset for each of the three inputs. The signals are then routed to a 45 MHz high performance analog-to-digital converter (ADC). The fully differential processing channel shows exceptional noise immunity, having a very low noise floor of –74dB. The 16-bit ADC has excellent dynamic performance making the LM98714 transparent in the image reproduction chain.
