100mW Stereo Amplifier Circuit based TL082

100mW Stereo Amplifier Circuit based TL082
This 100mW stereo amplifier is designed to integrate with a mixer, or can be used independently or as a basis for a multi-box headphone amplifier (box 4 headphone amplifiers for example). It operates under a balanced power supply with a range from + / -9 V and + / -18 V. The  100mW stereo amplifier based TL 082 circuit is based on the combination of op amp and an output stage (pseudo) two push-pull transistors, capable of delivering power

Dual Channel Headphone Amplifier

Dual Channel Headphone Amplifier
Here is a the circuit dual-channel headphone amplifier. The circuit is built with ic DA1 - KR1054UN1, KF1054UN1, AN7050, TDA7050T (SO8 all), TDA7050 (DIP8), which is more expensive than the previous the circuit single-channel headphone amplifier. All devices operate at supply voltage range 1.6-6V. Current, as well as in the single-channel headphone amplifier was not great. THD - 0.1%. Frequency 20-20000Hz. Limiting long-term power output at 32 ohms. (more…)

Single Channel Headphone Amplifier

Single Channel Headphone Amplifier
Headphone amplifier circuit was built by IC DA1 - KR1436UN1 (DIP8). This IC operated on a wide range of voltage between +2V-16V. With small current required, it can be powered by batteries. THD - 0.5%. Freq Frequency 20-20000Hz. Limiting long-term power output - 250mW 16 Ohm load and voltage 6V. (more…)
