AD9923A屬于集成電路（IC）的傳感器檢測器接口。由亞德諾半導體技術有限公司制造生產的AD9923A傳感器和檢測器接口該系列產品可執(zhí)行信號調節(jié)、數(shù)據轉換、激勵生成和/或各種將傳感器或變送器機構連接到主機設備所需的其他功能。示例包括用于 CCD 圖像傳感器的控制器、用于 4-20 mA 接口和類似應用的電流變送器、超聲變送器前端、惠斯通電橋接口等。

GENERAL DESCRIPTION

The AD9923A is a complete 36 MHz front-end solution for digital still cameras and other CCD imaging applications. Similar to the AD9923 product, the AD9923A includes the analog front end (AFE), a fully programmable timing generator (TG), and a 15-channel vertical driver (V-driver). A Precision Timing?core allows adjustment of high speed clocks with approximately 600 ps resolution at 36 MHz operation
