In digital circuit design, especially in microprocessor or measuring applications, it is often necessary to produce a clock signal by dividing down a master clock. The 4-chip solution sugges... Read more
When designing a precision outdoor temperature sensor it is a good idea to electrically isolate the sensor from the signal conditioning circuitry to protect it from voltage spikes such as mi... Read more
Constant frequency PWM Using 555-Timer With the basic astable circuit, the duty ratio cannot be controlled without affecting the frequency. Using the above circuit, it is possible to maintai... Read more
The MAX7378 contains two oscillators and a power-on reset circuit for microprocessors. The Speed input selects either 32.768 kHz (LF) or a higher frequency, which is pre-programmed. The type... Read more
Maxim (www.maxim-ic.com) has produced a completely self-contained TTLchip in a very small three-pin outline. The MAX7375 family of oscillators operates in the range of 1 MHz up to around 10... Read more
Crystals usually operate at fundamental frequencies up to about 15 MHz. Whenever higher frequencies are required a frequency multiplier is placed after the crystal oscillator. The resulting... Read more
In the LT1567 Linear Technology (www.linear-tech.com/ pdf/1567i.pdf) has produced a component specially developed for building analog filters with cutoff frequencies up to 5 MHz. It contains... Read more
Ronja is the author’s dog, a beagle-mongrel, who seems increasingly often to need to be called to heel either with a shout or with a whistle. And so the idea came about for an electronic dog... Read more
In Fall or Spring, the weather may be warm enough that we’d like to save money by shutting down the main heating system in our home and just use supplementary heating based on one or more el... Read more
From what’s written on the cover of Bert van Dam’s book entitled “50 New Applications for PIC Microcontrollers” [1], some of you might think that the projects, which address programming 16/1... Read more
