14-Bit, 125 MSPS A/D Converter ADS5500 and Its Application
Abstract: The ADS5500 is a 14-bit analog-to-digital converter by Texas Instrument in U.S.A for high-speed, high-precision, and ease of use. The digital output data is provided over a simple parallel interface that easily connects to DSPs. It aims at mainly the applications which need high-precision measurement and high-speed data gathering, such as wireless communication, communication receivers, base station infrastructure, test and measurement instrumentation, single and multichannel digital receivers, radar and infrared, video and imaging, medical equipment and so on. This paper introduces the performance, internal structure, pin descriptions and application consideration, and illuminates an application in video signal processing in brief.
