AD7653ASTZ集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書PDF中文資料

AD7653ASTZ屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD7653ASTZ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(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 AD7653 is a 16-bit, 1 MSPS, charge redistribution SAR analog-to-digital converter that operates from a single 5 V power supply. The part contains a high speed 16-bit sampling ADC, internal conversion clock, internal reference, error correction circuits, and both serial and parallel system interface ports. It features a very high sampling rate mode (Warp), a fast mode (Normal) for asynchronous conversion rate applications, and a reduced power mode (Impulse) for low power applications where power is scaled with the throughput. The AD7653 is fabricated using Analog Devices’ high performance, 0.6 micron CMOS process, with correspondingly low cost. It is available in a 48-lead LQFP and a tiny 48-lead LFCSP with operation specified from –40°C to +85°C.
