LM98516CCMTX

• Product Introduction

 Features   3.3V single power supply CD or S/H processes the polarity of negative input signals 32.5 MHz channel rate Enhanced ESD protection on timing and control pins Low-power CMOS design 4-wire serial interface 2. Symmetrical channel architecture Each channel has independent gain and offset correction Digital black level correction for each channel Digital white level calibration for each channel Programmable input clamping   Explanation   LM98519 is a fully integrated, high-performance 10-bit, 65 MSPS signal processing solution, digital color copier, scanner, and other image processing application solutions. With its innovative six-channel correlation dual sampling (CDS), or Sampling and Hold (Shanghai) sampling architecture, it achieves high-speed signal throughput. CDS/SH input stage settings with 1x or 2x gain. Each channel has a dedicated 1x to 10x (8-bit) PGA that allows precise gain adjustment for each channel. The digital white level automatic calibration loop can automatically set the PGA value to achieve the selected white target level. Each channel also features a ± 4-bit coarse, ± 10-bit fine analog offset correction DAC, allowing sampling and maintaining amplifier offset correction. These corrections can control the automatic digital black-level calibration loop. PGA and offset DAC, each channel programmed independently to achieve unique gain values and six channel offsets. A 2:1 multiplexing scheme route uses three 65MHz high-performance ADC signals. The fully differential processing channels achieve excellent noise immunity, with a very low noise level of 68 decibels. The 10-bit analog-to-digital converter offers excellent power performance and transparency LM98519 the image reproduction chain.
