壶,平底锅,日志,和线性数字电位器创建任意电压曲线

资料介绍
摘要:线性数字电位器,可用于任意电压曲线和波形。为数字电位器的替代名称是一个“字符串”数字 - 模拟转换器(DAC ) 。测井盆是线性锅产生对数响应的应用,如音频的艺术。

Pots, Pans, Logs, and Linear Digital Pots Create Arbitrary Voltage
Curves
By: Bill Laumeister

Abstract: Linear digital potentiometers can be used to make arbitrary voltage curves and waveforms. An
alternative name for a digital pot is a "string" digital-to-analog converter (DAC). Logging pots is the art of
making a linear pot produce a logarithmic response for a……
