Components Required
50 watt Bridge Mode Circuit
Bridge mode is commonly used in audio amplifier circuits like the TDA7265 IC for increased power output and driving low-impedance loads effectively( 50 watt at 8 ohms speakers ).
It will eliminates the need of an output coupling capacitor and can improve the signal-to-noise ratio. Additionally, bridge mode provides better speaker control, allowing for precise movement and improved audio reproduction.
Features of TDA7265
The Power Output of TDA7265
The TDA7265 can able to delivering a maximum power output of 25 watts per channel in stereo configuration (at 8 ohms load) or 50 watts in mono configuration (at 4 ohms load). This allows for decent audio performance and volume levels.
Operating Voltage
The typical operating voltage range for the TDA7265 is between 6 and 18 volts. This makes it compatible with a wide range of low-power audio systems, providing flexibility in its usage.
Bridge-Tied Load (BTL) Configuration
The TDA7265 supports a bridge-tied load configuration, enabling it to deliver higher output power compared to single-ended setups. In this mode, the IC can directly drive speakers without requiring an output coupling capacitor, simplifying the design.
Audio Quality
The TDA7265 is designed to deliver high-quality audio reproduction with low total harmonic distortion (THD) and noise.
This ensures clear and accurate sound output, without significant distortion or interference.
Protection Features
The IC incorporates important protection mechanisms. It includes built-in short-circuit protection, which safeguards the IC and connected speakers from damage in case of a short circuit or excessive load.
Additionally, the TDA7265 features thermal protection circuitry that prevents overheating. If the temperature exceeds a certain threshold, the amplifier either reduces power output or shuts down altogether to prevent damage.
Package
The TDA7265 is typically available in a multiwatt 11 package, which offers good thermal dissipation characteristics. This aids in heat management and ensures the IC operates within safe temperature limits.
