ADS7828集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS7828属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS7828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。

3 Description

The ADS7828 is a single-supply low-power 12-bit

data acquisition device that features a serial I2C interface and an 8-channel multiplexer. The analog-

to-digital converter (ADC) features a sample-and-hold

amplifier and internal asynchronous clock. The

combination of an I2C serial 2-wire interface and micropower consumption makes the ADS7828 ideal

for applications requiring the ADC to be close to the

input source in remote locations and for applications

requiring isolation. The ADS7828 is available in a

TSSOP-16 package.
