The TDA7439 is a volume, tone (bass, mid-range and treble) and balance (left/right) processor for high-quality audio applications in car-radio and Hi-Fi systems. Selectable input gain is provided. All the functions are controlled by serial bus. The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers. The TDA7439 employs BIPOLAR/CMOS technology to provide low distortion, low noise and DC stepping.
“After running my Arduino controlled Gainclone amp for the last 8 years, the LCD died and I decided that it was time for a revamp. This instructable is based on the original and is designed to be an ‘upgrade’ from …
“This is another version of a music device with an Arduino UNO, a Bluetooth receiver, an FM radio, a clock and a small IR remote, all with a small touch screen, so a combination of several of other Instructables that …
