ADI AD9253四路14位125MSPS模数转换解决方案

ADI公司的AD9253是集成了取样保持电路的四路14位125MSPS模数转换器(ADC),具有低成本,低功耗,体积小和容易使用的特点,工作电压1.8V,125MSPS速率时每路功耗为110mW,SNR = 74 dB ,SFDR = 90 dBc和DNL = ±0.75 LSB,满功率模拟带宽650MHz,可编程输出分辨率,主要用在超声波图像仪,高速取样,正交和多功能无线电接收器以及测试设备.本文介绍了AD9253产品亮点和主要特性,功能框图,以及AD9253CE01A评估板主要特性,电路图和材料清单.

The AD9253 is a quad, 14-bit, 80 MSPS/105 MSPS/125 MSPS analog-to-digital converter (ADC) with an on-chip sample- and-hold circuit designed for low cost, low power, small size, and ease of use. The product operates at a conversion rate of up to 125 MSPS and is optimized for outstanding dynamic performance and low power in applications where a small package size is critical.

The ADC requires a single 1.8 V power supply and LVPECL-/ CMOS-/LVDS-compatible sample rate clock for full performance operation. No external reference or driver components are required for many applications.
