ADS8326IB集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS8326IB属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS8326IB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 ADS8326 is a 16-bit, sampling, analog-to-digital

(A/D) converter specified for a supply voltage range

from 2.7V to 5.5V. It requires very little power, even

when operating at the full data rate. At lower data

rates, the high speed of the device enables it to

spend most of its time in the power-down mode. For example, the average power dissipation is less than

0.2mW at a 10kHz data rate.

The ADS8326 offers excellent linearity and very low

noise and distortion. It also features a synchronous

serial (SPI/SSI-compatible) interface and a differential

input. The reference voltage can be set to any level

within the range of 0.1V to VDD.

Low power and small size make the ADS8326 ideal

for portable and battery-operated systems. It is also a

perfect fit for remote data-acquisition modules,

simultaneous multichannel systems, and isolated

data acquisition. The ADS8326 is available in either

an MSOP-8 and an SON-8 package.
