An idea for design published in the April 2, 2001 issue, "Manually Operated Digital Pot Doesn't Need A Microprocessor," uses two proprietary ICs to manually control a digital potentiometer. After ...

A short while back, I published a design idea that uses a single linear pot to control the gain of a high performance OP37 decompensated op-amp over an unusually wide (-30 dB to +60 dB) range. Figure ...

It is now common for portable equipment to include some sort of stereo audio playback circuitry, perhaps for MP3 or Web radio applications. Many specialist ICs are available to use as building blocks ...

[Stephen Woodward] is familiar with digital potentiometers but is also familiar with their limitations. That spurred him to create the PWMPot which performs a similar function, but with better ...

Available in 10-, 50-, and 100-kOhm versions, the CAT5128 32-tap digital potentiometer is a simple up/down control for enabling easy-to-use digital interfaces. In an eight-lead SOT-23 package, the ...

The DP4 Series digital potentiometer is for ac and dc drive systems needing precise, repeatable speed setting and digital readout. The DP4 supports bipolar connections with power supplies of ±10 Vdc ...
