TC850CLW集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書PDF中文資料

TC850CLW屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由微芯科技股份有限公司制造生產(chǎn)的TC850CLW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。

GENERAL DESCRIPTION

The TC850 is a monolithic CMOS analog-to-digital converter (ADC) with resolution of 15-bits plus sign. It combines a chopper-stabilized buffer and integrator with a unique multiple-slope integration technique that increases conversion speed. The result is 16 times improvement in speed over previous 15-bit, monolithic integrating ADCs (from 2.5 conversions per sec up to 40 per sec). Faster conversion speed is especially welcome in systems with human interface, such as digital scales.
