Product Description
STMicroelectronics TDA7439DS13TR is a high-performance 2-channel audio power amplifier IC designed for use in car radios, hi-fi systems, and other quality audio applications. This integrated circuit provides volume, tone control (bass, mid-range, and treble), and left/right balance adjustment with precise increments, delivering superior audio experience.
The device features selectable input gain and a single stereo output to suit various audio input sources optimally. Using bipolar/CMOS technology, it ensures low noise and distortion levels as well as DC stepping capabilities for improved signal integrity.
Volume control and speaker attenuation are finely tunable in 1-dB steps, with independent mute and balance facilities to customize the audio output effectively. All functions are controlled digitally via a serial bus, enabling easy integration into modern audio system designs.
The TDA7439DS13TR is encapsulated in a compact 28-pin SO package measuring 17.7mm in length, 10mm in width, and 2.65mm in height, suitable for surface mount applications. It complies with RoHS environmental standards and operates reliably within an ambient temperature range of 0°C to 70°C. The product is manufactured in Malaysia.
Typical industrial use cases include audio amplification in automotive electronics, professional hi-fi audio equipment, and various consumer electronics where high-fidelity sound and precise audio tuning are required.
Volume, tone and balance processor for 2 audio channels. Selectable input gain for various source levels. Digital serial bus control for all functions. Low distortion and noise with bipolar/CMOS technology. Two independent speaker attenuators with mute and balance control.
Compact 28-pin SO surface mount package. Operating voltage range from 7V to 10.2V. Explore more Audio Amplifier ICs and related electronic components on EnvMart for your industrial and commercial projects.
