AD7853ARS集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書PDF中文資料

AD7853ARS屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD7853ARS模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器（ADC、A/D 或 A 轉(zhuǎn) D）對模擬信號進(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。一般來說，數(shù)字輸出是二進(jìn)制補碼二進(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。

GENERAL DESCRIPTION

The AD7853/AD7853L are high speed, low power, 12-bit ADCs that operate from a single 3 V or 5 V power supply, the AD7853 being optimized for speed and the AD7853L for low power. The ADC powers up with a set of default conditions at which time it can be operated as a read-only ADC. The ADC contains self-calibration and system-calibration options to ensure accurate operation over time and temperature and have a number of power-down options for low power applications.

FEATURES

Specified for VDD of 3 V to 5.5 V

Read-Only Operation

AD7853–200 kSPS; AD7853L–100 kSPS

System and Self-Calibration with Autocalibration on Power-Up

Low Power:

AD7853: 12 mW (VDD = 3 V)

AD7853L: 4.5 mW (VDD = 3 V)
