CS5451A-IS集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書PDF中文資料

CS5451A-IS屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由凌云邏輯制造生產(chǎn)的CS5451A-IS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(lái)說(shuō)，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 CS5451A is a highly integrated delta-sigma (ΔΣ)an alog-to-digital converter (ADC) developed for the power

measurement industry. The CS5451A combines six ΔΣ ADCs, decimation filters, and a serial interface on a single chip. The CS5451A interfaces directly to a current transformer or shunt to measure current, and to a resistive divider or transformer to measure voltage. The product features a serial interface for communication with a microcontroller or DSP.The product is initialized and fully functional upon reset, and includes a voltage reference.
