ADS7816U/2K5集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS7816U/2K5属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS7816U/2K5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。

DESCRIPTION

The ADS7816 is a 12-bit, 200kHz sampling analogto-

digital converter. It features low power operation

with automatic power down, a synchronous serial

interface, and a differential input. The reference voltage

can be varied from 100mV to 5V, with a corresponding

resolution from 24mV to 1.22mV.

Low power, automatic power down, and small size

make the ADS7816 ideal for battery operated systems

or for systems where a large number of signals must be

acquired simultaneously. It is also ideal for remote

and/or isolated data acquisition. The ADS7816 is

available in an 8-pin plastic mini-DIP, an 8-lead SOIC,

or an 8-lead MSOP package.
