- LED-current limiter accepts ac or dcLED drivers have lots of features and require plenty of external components. When your application requires no PWM (pulse-width-modulated) dimming or controlled frequency operation, your primary concern may be that too much current could damage or destroy your LEDs. In this...Jul 18, 2023
- Calibrated Noise Test Setup Increases Measurement RepeatabilityThis circuit increases the repeatability of noise test setups by providing reference points in the noise-vs.-frequency output generated by the network analyzer. It's based on Maxim MAX4475, MAX427, and MAX4101 op amps. Noise measurements can be problematic. They often...Aug 11, 2021
- Derive a simple high-current source from a lab supplyWhen electronic testing requires an adjustable current source, you must often build that piece of test equipment in the lab. You can easily make such a current source from a standard force-sense lab power supply (Figure 1). The circuit requires an additional power supply for the...Feb 1, 2017
