Circuit delivers constant power to a load
If you have a load with a variable or poorly specified resistance and want to regulate the power applied to it (a heater for example), merely controlling the voltage or current will not work, as in both cases the power P = I2R = V2/R depends on R...
Vishay Intertechnology releases AEC-Q100 qualified ambient light sensor in rectangular 4.38 mm x 1.45 mm x 0.6 mm package
Vishay Intertechnology introduced the industry’s first AEC-Q100 qualified rectangular ambient light sensor....
LM4041 voltage regulator impersonates precision current source
The LM4041 has been around for over 20 years. During those decades, while primarily marketed as a precision adjustable shunt regulator, this classic device also found its way into alternative applications...
A high-performance current source
The ever innovative and prolific Mr. Woodward has offered “PWM-programmed LM317 constant current source”, an intriguing programmable constant current source which elicited a lively conversation in its comments section...
Current monitor
Almost every wall power supply has no indicator showing whether current is consumed by the load or not. It seems that this was a shortcoming that was not only noticed by me...
Another simple flip ON flop OFF circuit
Figure gives a simple circuit for the PUSH ON, PUSH OFF function with only a few inexpensive components...
A negative current source with PWM input and LM337 output
Figure’s negative constant current source has been a textbook application for the LM337 regulator forever...
Simple logic probe uses bicolor LED
When probing digital logic levels on a circuit board, locating the indicator of the logic level near the probe tip is convenient, so that you can keep both the indicator and probe tip constantly in sight...
Digital potentiometers enable programmable biquadratic filter
Of the many types of analog filters available to designers, few allow easy adjustments of the filter parameters. The biquadratic, or biquad, filter is an exception, however...
