Control systems are becoming increasingly dependent on digital processing and so require sensors able to provide direct digital inputs. Sensors based on time measurement, having outputs based on a frequency or phase, have an advantage over conventional analogue sensors in that their outputs can be measured directly in digital systems by pulse counting.

ADC制造商在數(shù)據(jù)手冊中定義ADC性能的方式令人困惑，并且可能會在應(yīng)用開發(fā)中導(dǎo)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(shù)，卻經(jīng)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(tài)范圍、噪聲層的關(guān)系，以及在諸如計量等應(yīng)用中的含義。

A tutorial on SAR type A/D converters, this note contains detailed information on several 12-bit circuits. Comparator, clocking, and preamplifier designs are discussed. A final circuit gives a 12-bit conversion in 1.8µs. Appended sections explain the basic SAR technique and explore D/A considerations.

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.
