AD9434集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

AD9434属于集成电路（IC）的模数转换器（ADC）。由亚德诺半导体技术有限公司制造生产的AD9434模数转换器（ADC）模数转换器（ADC、A/D 或 A 转 D）对模拟信号进行采样，例如由麦克风采集的声音或传感器的输出，然后将其转换为数字信号。一般来说，数字输出是二进制补码二进制数，与输入成比例。输入类型可能是差分、伪差分或单端输入。模数转换器可按照位数、采样率、输入数、接口、转换器数和架构（例如自适应增量、双斜率、折叠、流水线、SAR、三角积分、两步式）进行选择。

GENERAL DESCRIPTION

The AD9434is a 12-bit monolithic sampling analog-to-digital converter (ADC) optimized for high performance, low power, and ease of use. The part operates at up to a 500 MSPS conversion rate and is optimized for outstanding dynamic performance in wideband carrier and broadband systems. All necessary functions, including a sample-and-hold and voltage reference, are included on the chip to provide a complete signal conversion solution. The VREF pin can be used to monitor the internal reference or provide an external voltage reference (external reference mode must be enabled through the SPI port).
