Common emitter non-symmetrical gain – I have simulated in LTspice a very simple CE amplifier. There is no AC capacitor at the emitter It is a plain and simple CE emitter bias unbypassed with a gain of Av = -Rc / RE = 4.07. It turns out that, as input is a perfect 1V sine […]
New digital power amplifiers for car audio deliver Cleaner Sound and Simplify System Design
STMicroelectronics (NYSE: STM), is extending its lead in digital automotive-audio technologies by launching a second generation of power amplifiers that simplify design for car-radio system suppliers and deliver better listening experiences to drivers and passengers – even in smaller cars. ST’s new, second-generation FDA801 and FDA801B 4-channel class-D[1] amplifiers with digital input convert the digital […]
Audio op amp puts out 150 mW
Texas Instruments introduced an audio operational amplifier (op amp) that sets the latest standard in audio performance. The OPA1622 is the newest addition to the company’s Burr-Brown™ Audio line and is the next generation of the widely adopted OPA1612. The new OPA1622 delivers high output power of up to 150 mW and extremely low distortion […]

Amplifying DC voltage from 5V to 12V – I use an Arduino board with a 5V output supply but I Ineed to operate 12V motor. I know that I could connect the Arduino to a 12V power supply to solve the problem. But but I can’t do it for some of reason so I have to build […]
High-resolution audio processing SoC
ON Semiconductor has released its latest high-resolution audio processing System-on-Chip with 1656KB SRAM and power-efficient hardware acceleration, bringing extra space savings and longer battery life to devices such as smartphones, wearable accessories and voice recorders. Powering the LC823450 are a highly efficient ARM Cortex-M3 core and ON Semiconductor’s 32-bit/192kHz audio-processing engine with hardware-based MP3 encoding/decoding and […]
