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…)
