The FM receiver module is based on the TEA5767 [1, 2] chip. It is a well-known module that could be controlled via the I2C bus. It covers the FM frequency range from 76MHz to 108MHz. At the output, it ...

A DC motor can be switched ON and OFF using this amplifier circuit while being able to regulate its spinning speed with a PWM source generator. The circuit is using the pin 9, 10, and 11 from the ...

Arguably, the ATmega328P is being left behind as ‘the Arduino processor’ because Arduino’s are following the rest of the world and going 32bit.

You can take an op amp with rare input characteristics and elevate it to achieve higher voltage range, better gain accuracy, higher slew rate, and less distortion than the original op amp. I was ...

The ADHV4710 op amp operates on dual supplies from ±12 to ±55 V, delivering output current of ±100 mA at the higher voltages. A ±1,300-V/μs output slew rate into capacitive loads up to 1 nF (1000 pF).

A simple linear voltage-controlled amplifier can be constructed with one op amp and two JFETs (see the figure). The amplifier can achieve an 80-dB dynamic control ...
