TDA7233

Overview

The TDA7233 is a monolithic Class AB audio power amplifier IC designed for portable applications. It operates on a supply voltage range of 1.8V to 15V and delivers up to 1W total power dissipation at 50°C ambient temperature. The device features an external mute or power-down function, improved supply voltage rejection, low quiescent current, and high power capability with low crossover distortion.

Feature Summary

• Integrated Class AB power amplifier architecture
• Supports external mute or power-down control functions
• Optimized for low quiescent current consumption
• Features improved supply voltage rejection characteristics

Applications

• Portable players
• Cordless telephones
• Cellular radios

Procurement Notes

Verify the specific package variant required for your design, as the TDA7233 is available in both 8-pin Minidip and SO8 configurations. Confirm that the selected component matches the exact part number designation corresponding to your chosen physical footprint before finalizing procurement orders.

Selection Notes

Select this component when designing battery-powered systems requiring a compact Class AB amplifier solution. Ensure the application environment stays within the specified -40°C to 150°C junction temperature range and that the supply voltage does not exceed the absolute maximum rating of 16V.

Part Context

This integrated circuit belongs to STMicroelectronics' portfolio of audio amplifiers intended for consumer electronics. It utilizes advanced semiconductor technology to provide efficient audio signal amplification while maintaining low power consumption suitable for mobile devices.

Replacement Considerations

TDA7233D serves as the equivalent part number representing the same functional specifications but packaged in the SO8 format instead of the standard Minidip configuration.
