TDA7449 STMicroelectronics | Digitally Controlled Audio Processor - AICCHIP

Product Overview: TDA7449

The TDA7449 is a high-quality, digitally controlled audio processor manufactured by STMicroelectronics. Designed specifically for TV, car radio, and home Hi-Fi applications, this monolithic IC integrates volume control, tone control (bass and treble), and input multiplexing into a single chip. It is fully programmable via a standard I²C bus interface, allowing microcontrollers to easily manage complex audio routing and equalization tasks. Featuring low noise, low distortion, and smooth step-volume transitions, the TDA7449 provides an elegant solution for legacy audio signal processing. Although classified as Obsolete (EOL) by the manufacturer, it remains highly sought after for the repair, maintenance, and remanufacturing of established consumer audio electronics.
