THE TOP 10 OPERATIONAL AMPLIFIERS ON SNAPEDA

The operational amplifier – or “op amp” for short – is a common building block in analog electronics. Whether you’re a professional electronics designer or just getting started, it is likely you’ve used an op amp in your designs. Invented in 1941 by Karl D. Swartzel Jr. of Bell Labs, the op amp was originally built with vacuum tubes and was invented to perform mathematical operations in analog computers, he ...

USB POWERED AUDIO AMPLIFIER USING MAX4298

USB powered mini speaker amplifier is conveniently powered by USB and it is simple to set up. USB powered speakers are convenient for listening to your media while at home or on the go. Conventional computer speakers that require an electrical outlet to work can be prohibitive because they force you to be close to the power supply at all times. This audio amplifier is directly connected to a USB port and to ...

6CY7 DUAL TRIODE VALVE AMPLIFIER

I’ve always wanted to know what the “tube magic” was all about. There is much opinion in the science of music production, probably because music and its perception is highly personal and subjective. Ive always imagined that since transistor amplifiers were “perfect” with their large amounts of negative feedback, great linearity, and low THD that tube amplifiers must add something to sound that generates the ...

Temperature-to-period circuit provides linearization of thermistor response

Designers often use thermistors rather than other temperature sensors because thermistors offer high sensitivity, compactness, low cost, and small time constants. But most thermistors’ resistance-versus-temperature characteristics are highly nonlinear and need correction for applications that require a linear response. Using a thermistor as a sensor, the simple circuit in Figure 1 provides a time period var ...
