Pots, Pans, Logs, and Linear Digital Pots Create Arbitrary Voltage Curves

资料介绍
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 applications such as audio.
