TDA7297 power amplifier board

This is a powerful and compact amplifier board based on the proven and reliable TDA7297 chip from STMicroelectronics. It is the perfect solution for anyone looking to easily build their own stereo amplifier with an excellent price/performance ratio. The board delivers 15W + 15W of power into 4Ω speakers (or 7W + 7W into 8Ω), making it ideal for home use, small desktop systems, or portable speakers with an external power supply.

Key Advantages & Specifications:

• TDA7297 Chip: Guarantees low distortion (THD ~0.1%), low noise, and clean, detailed sound.

• Easy Connection: Includes convenient screw terminals for power and speakers, as well as standard RCA inputs for connecting to phones, computers, TVs, etc.

• Simple Power Supply: Operates with a standard DC voltage from 9V to 15V (12V optimal). Recommended current ≥ 2A.

• Built-in Protections: Features over-temperature and short-circuit protection for greater reliability.

• Compact Dimensions: Approximately 65mm x 45mm (version with volume potentiometer: ~53x48x42mm), easy to mount in various enclosures.

• Impedance Range: Compatible with 4Ω to 8Ω speakers.

Who is it for?
This module is perfect for DIY enthusiasts, electronics beginners, and anyone wanting to improve or create a simple audio system. It is an excellent foundation for:

• A desktop amplifier for a computer or TV.

• A sound system for a small room.

• A DIY portable speaker.

• A practice guitar amplifier.

Important: An external 12V/2A power supply and two speakers are required for operation and are not included in the kit. For the cleanest sound without noise, using a stable linear power supply (transformer-based) or a quality battery is recommended.
