TDA2004Raudio amplifier
The TDA2004R is a Class B dual-channel stereo audio power amplifier developed by STMicroelectronics, supplied in through-hole Multiwatt11 package with tube packaging, originally optimized for automotive radio audio systems. Operating within 8 V to 18 V single supply voltage and rated for junction temperature range from -40 °C to 150 °C, this amplifier delivers 10 W + 10 W continuous output power under typical 14.4 V vehicle supply condition, supporting speaker loads as low as 1.6 Ω with peak output current capacity up to 3.5 A. It requires minimal external peripheral components and allows direct contact between the package tab and heatsink without electrical insulation, simplifying thermal layout and enabling compact audio power designs for automotive and general audio equipment.
This stereo amplifier features low audio distortion and low background noise to reproduce clean audio signals, while integrating comprehensive built-in protection circuits to adapt to harsh automotive electrical environments. Embedded safeguards include AC output short-circuit protection, thermal shutdown against overheating, load dump surge protection, open-ground fault protection and immunity to inductive speaker loads, preventing permanent chip damage under abnormal operating conditions. The device supports flexible circuit configuration for stereo playback or single-channel bridged power booster mode, and its stable gain characteristic eliminates complicated frequency compensation networks, lowering overall BOM cost and shortening hardware debugging cycles for audio amplifier projects.
Alternative Class B amplifier Models
● TDA2005R (STMicroelectronics): Multiwatt11 packaged Class B stereo audio amplifier with higher output power and enhanced load driving capability, serving as a direct upgrade option for automotive stereo audio applications.
● TDA7377 (STMicroelectronics): Dual-channel automotive audio power amplifier with rich built-in protection and flexible configuration, compatible with mainstream car audio platform circuit frameworks.
● KA2206B (Samsung): Through-hole dual-channel Class B audio power amplifier with comparable power rating and simple peripheral circuits, a cost-effective second-source alternative for consumer stereo amplifiers.
