AD7738BRU集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

AD7738BRU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AD7738BRU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 AD7738 is a high precision, high throughput analog front end. True 16-bit p-p resolution is achievable with a total conversion time of 117 µs (8.5 kHz channel switching), making it ideally suitable for high resolution multiplexing applications.
