摘要:本应用笔记介绍了一种简单,独立的面板显示电路,驱动12个LED的数列。 LED的列是一个与6分贝台阶高度12步的日志指标,形成一个72分贝的总列范围。电路的精度和稳定性,是指所设计的ADC的规格。 MAX1276 12位ADC的特点。Maxim > App Notes > A/D and D/A Conversion/Sampling Circuits Display Drivers Keywords: logarithmic panel displays, LED panels, analog-digital converters, ADCs Sep 21, 2009 APPLICATION NOTE 4442 Logarithmic LED Panel Display Has 72dB Range By: Tamer Mogannam Abstract: This application note presents a simple, stand-alone panel-display circuit that drives a 12-LED logarithmic column. The LED column is a 12-step log indicator with 6dB step height, forming a total column range of 72dB. The circuit's accuracy and stability are defined by the specifications for the design's ADC. The MAX1276 12-bit ADC is featured. This design idea appeared in the October 31, 2006 issue of EE Times magazine. Panel-level logarithmic-column displays are usually built i……
