AD9650-105EBZ

• Product Introduction

AD9650-105EBZ 16-bit, 25 MSPS/65 MSPS/80 MSPS/105 MSPS analog-to-digital converter  

The AD9650 is a dual-channel, 16-bit, 25 MSPS/65 MSPS/80 MSPS/105 MSPS analog-to-digital converter (ADC) designed to digitize high-frequency, wide dynamic range signals with input frequencies up to 300 MHz.

This dual-channel ADC features a multi-stage, differential pipeline architecture with integrated output error correction logic. Each ADC features a wide-bandwidth, differential sample-holding analog input amplifier and shares an integrated voltage reference to simplify design. The duty cycle stabilizer can be used to compensate for fluctuations in the ADC clock duty cycle, allowing the converter to maintain excellent performance.

ADC output data can be routed directly to two external 16-bit output ports or multiplexed on a single 16-bit bus. These outputs can be set to 1.8 V CMOS or LVDS.

Flexible power-down options can significantly reduce power consumption when needed.

Programming of setup and control is done using a three-wire SPI-compatible serial interface.

The AD9650 is available in a 64-pin LFCSP package and is rated for an industrial temperature range of −40°C to +85°C.

Product Focus

1. 片内扰动选项可改善低功耗模拟输入信号的无杂散动态范围(SFDR)性能。
2. 取得专利的差分输入在最高至300 MHz的输入频率下仍保持出色的信噪比(SNR)性能。
3. 采用1.8 V单电源供电，数字输出驱动器则采用独立电源供电，以支持1.8 V CMOS或LVDS输出。
4. 标准串行端口接口(SPI)支持各种产品特性和功能，例如：数据格式化（偏移二进制、二进制补码或格雷码）、时钟DCS使能、掉电模式和测试模式等。
5. 与AD9268和其它双通道系列，如AD9269、AD9251、AD9231以及AD9204引脚兼容，可以轻松换用不同分辨率和带宽的产品。
