TDA7267T

Overview

The TDA7267T is a Class AB mono audio amplifier in an 8-pin DIP package. It delivers 2 W output power into an 8 Ω load at 12 V supply with 10% THD. The device operates on a supply voltage range of 4.5 V to 18 V and features an internally fixed gain of 32 dB. Key electrical characteristics include a total quiescent current of 30 mA maximum, a standby current of 0.3 mA maximum, and a junction-to-ambient thermal resistance of 76 °C/W.

Feature Summary

• Rail-to-rail voltage swing capability without bootstrap capacitors
• Integrated thermal protection and AC short-circuit protection
• Low turn-on/off pop noise generation
• Standby mode operation for low power consumption

Applications

• TV audio systems
• Portable radio applications
• Mono speaker amplification

Procurement Notes

Verify the component status as obsolete before procurement planning. Confirm that the DIP-8 tube packaging aligns with assembly requirements. Ensure design compatibility with the specified operating temperature range of 0°C to 70°C. Review the datasheet for absolute maximum ratings to prevent operational damage during integration.

Selection Notes

Select this component for designs requiring a simple mono amplifier solution with minimal external components. The absence of feedback capacitors and Boucherot cells simplifies the circuit layout. Consider the thermal dissipation requirements when designing the PCB copper area, as heat management is critical for maintaining performance within the specified ambient temperature limits.
