DESCRIPTION

· The LM98714 is a fully integrated, high-performance 16-bit, 45MSPS signal processing solution designed for digital color copiers, scanners, and other image processing applications. It features high-speed signal throughput using Correlated Double Sampling (CDS) or Sample and Hold (S/H) inputs, 8-bit Programmable Gain Amplifiers (PGA), and a ±9-Bit offset correction DAC. The device includes independently controlled Digital Black Level correction loops for each input and routes signals to a 45 MHz high-performance analog-to-digital converter (ADC), ensuring exceptional noise immunity and transparency in the image reproduction chain.
