AD9445集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

AD9445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AD9445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 AD9445 is a 14-bit, monolithic, sampling analog-to-digital converter (ADC) with an on-chip IF sampling track-and-hold circuit. It is optimized for performance, small size, and ease of use. The product operates at up to a 125 MSPS conversion rate and is designed for multicarrier, multimode receivers, such as those found in cellular infrastructure equipment.
