LM98620的产品详情:

The LM98620 is a fully integrated, 10–Bit, 70 MSPS signal processing solution for high performance digital color copiers, scanners, and other image processing applications. High-speed signal throughput is achieved with an innovative six channel architecture utilizing Correlated Double Sampling (CDS), or Sample and Hold (SH) type sampling. Gain settings of 1x or 2x are available in the CDS/SH input stage. Each channel has a dedicated 1x to 10x (8 bit) PGA that allows accurate gain adjustment. The Digital White Level auto calibration loop can automatically set the PGA value to achieve a selected white target level. Each channel also has a ±4 bit coarse and ±10 bit fine analog offset correction DAC that allows offset correction before the sample-and-hold amplifier. These correction values can be controlled by an automated Digital Black Level correction loop. The PGA and offset DACs for each channel are programmed independently allowing unique values of gain and offset for each of the six channels. A 2-to-1 multiplexing scheme routes the signals to three 70 MHz high performance ADCs. The fully differential processing channels achieve exceptional noise immunity, having a very low noise floor of –68.5dB. The 10 bit analog-to-digital converters have excellent dynamic performance, making the LM98620 transparent in the image reproduction chain.
