TDA7297 sound amplifier Chip

Description:

The TDA7297 is a high-performance, dual-channel bridge amplifier integrated circuit (IC) designed for audio applications requiring efficient power amplification with minimal external components. It delivers a total output power of 30W (15W per channel) into a 4-ohm load, making it suitable for various audio systems, including portable radios, TVs, and small home audio setups.

Key Features:

• Dual bridge amplifier configuration for efficient power output
• High output power: 15W per channel into a 4-ohm load
• Wide supply voltage range (6V to 18V) for flexibility
• Minimal external components required (no SVR capacitor, no bootstrap, no Boucherot cells)
• Internally fixed gain for simplified design
• Stand-by and mute functions for power saving and audio control
• Short circuit and thermal overload protection

Technical Specifications:

• Package Type: SOIC-16
• Supply Voltage: 6V to 18V
