描述 Description

The MCP3302 13-bit Analog to Digital Converter (ADC) features full differential inputs and low power consumption in a small package that is ideal for battery powered systems and remote data acquisition applications. The industry-standard SPI? serial interface enables 13-bit ADC capability to be added to any PICmicro? microcontroller. The MCP3302 features 100k samples/second, 1 input channel, low power consumption (300 nA typical standby, 450μA maximum active), and is available in 14-pin PDIP, SOIC and TSSOP packages. The full differential inputs of the MCP3302 enable a wide variety of signals to be used in applications such as remote data acquisition, portable instrumentation, and battery operated applications.

簡介

MCP3302屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由制造生產(chǎn)的MCP3302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(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。
