DIY audio amplifiers circuit diagram electronics projects and other related audio projects like : power amplifiers, audio systems, audio filters, vu meters, tone control, audio equalizers and more .
This 12 watt audio amplifier circuit is based on the TDA1519 integrated circuit which can be used in audio applications that don’t need high output power .
The LM48824 is a Class G, ground-referenced stereo headphone amplifier designed for portable devices which draws only 0.9 mA (typical) of quiescent current to double the audio playback time of smart phones, full-featured mobile phones and portable music players.
The LM48824’s Stereo headphone amplifier (Class G architecture ) increases audio (MP3, mobile TV, etc.) playback time with its adaptive power supply approach that enables very low supply rails, which doubles the power-efficiency compared to typical Class AB headphone amplifiers.
The LM49352 mixed-signal audio subsystem circuit and LM49151 analog subsystem are targeted at smart phones, full-featured phones, portable gaming devices and portable GPS devices.
