HIGH-QUALITY HEADPHONE AMPLIFIER - PRINTED PLATE
Description
Listening to music through headphones can be a source of many great aesthetic experiences, provided, however, that the amplifier is of sufficient quality. Therefore, we propose to make a headphone amplifier characterized by very good parameters despite the uncomplicated construction. The two-channel power amplifier bases its construction on the TDA7233 amplifier. For the correct operation, a minimum number of elements is required, which makes the project very simple. To the stereo minijack output connector we connect magnetodynamic headphones with an impedance greater than 2 ohms. The best results are achieved with headphones with impedance of 32 ohms / channel.
Recommendations: the device is especially recommended for enthusiasts of good sound, music lovers and musicians
Selected parameters:
- Power amplifier operating class: AB
- Output power (Rl = 32 ohms, Ucc = 12V): 800 mW
- Nonlinear distortion: less than 0.3%
- Frequency response 17 Hz ... 23 kHz
- Input impedance: 90 cells
- Permissible voltage range: 1.8 ... 15V AC or DC
- Power consumption at rest (per channel): approx. 6 mA
- The printed circuit board and documentation are included
A version with a set of components for self-assembly is available
