CS5506集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書PDF中文資料

CS5506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CS5506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。

Description

The CS5505/6/7/8 are a family of low power CMOS A/D converters which are ideal for measuring low-frequency signals representing physical, chemical, and biological processes.

The CS5507/8 have single-channel differential analog and reference inputs while the CS5505/6 have four pseudo-differential analog input channels. The CS5505/7 have a 16-bit output word. The CS5506/8 have a 20-bit output word.The CS5505/6/7/8 sample upon command up to 100 Sps.

The on-chip digital filter offers superior line rejection at 50 and 60 Hz when the device is operated from a 32.768 kHz clock (output word rate = 20 Sps).

The CS5505/6/7/8 include on-chip self-calibration circuitry which can be initiated at any time or temperature to ensure minimum offset and full-scale errors.

The CS5505/6/7/8 serial port offers two general-purpose modes for the direct interface to shift registers or synchronous serial ports of industry-standard microcontrollers.
