描述 Description

The MCP3202 12-bit Analog-to-Digital Converter (ADC) combines high performance and low power consumption in a small package, making it ideal for embedded control applications. The MCP3202 features a successive approximation register (SAR) architecture and an industry-standard SPI? serial interface, allowing 12-bit ADC capability to be added to any PICmicro? microcontroller. The MCP3202 features 100k samples/second, 2 input channels, low power consumption (5nA typical standby, 550 μA max. active), and is available in 8-pin PDIP, SOIC and TSSOP packages. Applications for the MCP3202 include data acquisition, instrumentation and measurement, multi-channel data loggers, industrial PCs, motor control, robotics, industrial automation, smart sensors, portable instrumentation and home medical appliances.

簡介

MCP3202屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由制造生產(chǎn)的MCP3202模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器（ADC、A/D 或 A 轉(zhuǎn) D）對模擬信號進行采樣，例如由麥克風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)字輸出是二進制補碼二進制數(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）進行選擇。
