TDA7297 15W+15W Dual Channel Amplifier

The TDA7297 is a compact dual-bridge audio amplifier IC built for anyone assembling a small yet powerful stereo sound system, whether for a DIY speaker project, TV audio upgrade, or portable radio build. Operating in Class AB with a bridge-tied-load (BTL) configuration, this chip eliminates the need for bulky output capacitors while delivering strong power efficiency from a wide 6V to 18V supply range, making it flexible enough for both battery-powered and adapter-driven setups.

Each channel is capable of driving a 15W speaker, giving a combined 30W of stereo output when paired with 4Ω to 8Ω speakers, more than enough volume for small rooms, workshops, or personal audio setups. Because the gain is internally fixed, minimal external components are required to get the amplifier running, which keeps the bill of materials low and simplifies board design for hobbyists building their own amplifier circuits from scratch.

Built-in mute and standby functions help eliminate the annoying pop and click noises that often occur during power-on and power-off transients, while short-circuit and thermal overload protection add a layer of safety during extended use. Adequate heatsinking is recommended, especially at higher volumes, to keep the chip operating reliably. This makes the TDA7297 a solid choice for makers building compact amplifier boards, portable speakers, or home audio upgrades.
