TDA7449 Description

Short technical summary and product information.

The TDA7449 is an integrated circuit audio processor from STMicroelectronics, designed for quality audio applications in TV systems. This device features a selectable input multiplexer with 2 stereo inputs and one stereo output, allowing for optimal adaptation to different sources. It provides comprehensive control over audio settings, including treble and bass adjustments in 2.0dB steps, and volume control in 1.0dB steps. Additionally, it includes two independent speaker attenuators for balance facility and an independent mute function. All functions are programmable via a serial bus interface, specifically I²C.

 

The TDA7449 is housed in a 20-DIP (0.300", 7.62mm) package and is designed for Through Hole mounting. It operates within a supply voltage range of 6V to 10.2V and an ambient temperature range of 0°C to 70°C. The AC signal setting is achieved through resistor networks and switches combined with operational amplifiers, utilizing BIPOLAR/CMOS Technology for low distortion and low noise.

 

This audio processor is suitable for consumer audio applications and is RoHS3 Compliant. Its features make it a versatile component for enhancing audio performance in various electronic devices.
