ADC制造商在數據手冊中定義ADC性能的方式令人困惑,并且可能會在應用開發中導致錯誤的推斷。最大的困惑也許就是“分辨率”和“精確度”了——即Resolution和Accuracy,這是兩個不同的參數,卻經常被混用,但事實上,分辨率并不能代表精確度,反之亦然。本文提出并解釋了ADC“分辨率”和“精確度”,它們與動態范圍、噪聲層的關系,以及在諸如計量等應用中的含義。

A complete design for a data acquisition card for the IBM PC is detailed in this application note. Additionally, C language code is provided to allow sampling of data at speed of more than 20kHz. The speed limitation is strictly based on the execution speed of the "C" data acquisition loop. A "Turbo" XT can acquire data at speeds greater than 20kHz. Machines with 80286 and 80386 processors can go faster than 20kHz. The computer that was used as a test bed in this application was an XT running at 4.77MHz and therefore all system timing and acquisition time measurements are based on a 4.77MHz clock speed.

This application note describes a Linear Technology "Half-Flash" A/D converter, the LTC1099, being connected to a 256 element line scan photodiode array. This technology adapts itself to handheld (i.e., low power) bar code readers, as well as high resolution automated machine inspection applications..

Highlights the LTC1062 as a lowpass filter in a phase lock loop. Describes how the loop's bandwidth can be increased and the VCO output jitter reduced when the LTC1062 is the loop filter. Compares it with a passive RC loop filter. Also discussed is the use of LTC1062 as simple bandpass and bandstop filter.
