ADS8321集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書PDF中文資料

ADS8321屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由德州儀器制造生產(chǎn)的ADS8321模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器（ADC、A/D 或 A 轉(zhuǎn) D）對(duì)模擬信號(hào)進(jìn)行采樣，例如由麥克風(fēng)采集的聲音或傳感器的輸出，然后將其轉(zhuǎn)換為數(shù)字信號(hào)。一般來說，數(shù)字輸出是二進(jìn)制補(bǔ)碼二進(jìn)制數(shù)，與輸入成比例。輸入類型可能是差分、偽差分或單端輸入。模數(shù)轉(zhuǎn)換器可按照位數(shù)、采樣率、輸入數(shù)、接口、轉(zhuǎn)換器數(shù)和架構(gòu)（例如自適應(yīng)增量、雙斜率、折疊、流水線、SAR、三角積分、兩步式）進(jìn)行選擇。

DESCRIPTION

The ADS8321 is a 16-bit sampling analog-to-digital converter

(ADC) with tested specifications over a 4.75V to

5.25V supply range. It requires very little power even when

operating at the full 100kHz 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—the average power dissipation

is less than 1mW at 10kHz data rate.

The ADS8321 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

500mV to VCC/2.

Ultra-low power and small size make the ADS8321 ideal

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

perfect fit for remote data acquisition modules, simultaneous

multi-channel systems, and isolated data acquisition.

The ADS8321 is available in an MSOP-8 package.
