TDA7233D013TR

Overview

The TDA7233D013TR is a monolithic Class AB audio amplifier IC from STMicroelectronics, designed for portable applications. It operates on a supply voltage range of 1.8V to 15V and delivers up to 1W output power into an 8-ohm load at 12V. Key electrical characteristics include a closed-loop voltage gain of 39dB, input bias current of 100nA, and mute attenuation of 70dB. The device features low quiescent current (3.6mA in mute high state) and improved supply voltage rejection of 45dB at 100Hz.

Feature Summary

• Integrated external mute or power down function for flexible control
• Low crossover distortion for high-fidelity audio reproduction
• High power capability within a compact package design

Applications

• Portable players
• Cordless telephones
• Cellular radios

Procurement Notes

Verify the specific suffix '013TR' against official documentation to confirm tape-and-reel packaging details, as datasheets may list standard Minidip or SO8 packages without explicit reel specifications. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the component matches the exact manufacturer part number to avoid compatibility issues with existing designs.

Selection Notes

Select this component for designs requiring a single-channel mono amplifier with wide supply voltage flexibility. It is suitable for battery-powered devices due to low quiescent current consumption. Consider the thermal resistance limits when designing for maximum power dissipation scenarios. Verify that the required output power aligns with the specified load impedance and supply voltage conditions.

Part Context

The TDA7233 series is a Class AB power amplifier intended for use in portable electronics. It is available in 8-pin Minidip or SO8 packages. The device is optimized for applications where space and power efficiency are critical constraints. It provides a cost-effective solution for audio amplification in consumer electronic devices.

Replacement Considerations

Check for direct pin-compatible alternatives if the TDA7233D013TR is unavailable. Ensure any substitute maintains the same operating voltage range and output power capabilities. Verify that the replacement supports the required mute functionality and thermal performance characteristics.
