TDA2003H

TDA2003H Description

The TDA2003H by STMicroelectronics is a monolithic Class AB audio amplifier IC designed for robust performance in low-to-medium power audio applications. Housed in a 5-pentawatt package, it delivers 12W output power into a 1.6Ω load with a supply voltage range of 8V to 18V, making it suitable for automotive and portable audio systems. This obsolete part remains relevant for legacy designs due to its reliability and ease of integration. Compliant with ROHS3 and REACH Unaffected standards, it is ideal for environmentally conscious designs. The through-hole mounting ensures mechanical stability, while its non-MSLA (Moisture Sensitivity Level Not Applicable) status simplifies handling and storage.

TDA2003H Features

• High Output Power: Delivers 12W mono output at 1.6Ω, ensuring loud and clear audio reproduction.
• Wide Voltage Range: Operates from 8V to 18V, accommodating various power supply configurations.
• Class AB Efficiency: Balances power efficiency with low distortion for high-fidelity audio.
• Robust Packaging: 5-pentawatt through-hole design enhances thermal dissipation and durability.
