TDA7266M

Overview

The TDA7266M is a mono bridge amplifier from STMicroelectronics, designed for TV and portable radio applications. It operates on a wide supply voltage range of 3V to 18V with a maximum output power of 7W into an 8-ohm load. The device features internally fixed gain, standby and mute functions, and includes short-circuit and thermal overload protection. It requires minimum external components, eliminating the need for SWR capacitors, bootstrap circuits, or Boucherot cells.

Feature Summary

• Mono bridge amplifier architecture optimized for single-channel audio output
• Integrated protection mechanisms including short-circuit and thermal overload safeguards
• Operational capability with minimal external component count due to internal circuit design
• Supports standby and mute control functions for system power management

Applications

• Television sets
• Portable radios
• Portable audio devices

Procurement Notes

Verify the specific suffix 'M' indicates the mono bridge configuration distinct from other TDA7266 variants. Confirm package type and pinout compatibility during integration. Check current production status as some related models may be discontinued. Ensure supply chain sources provide authentic STMicroelectronics components to avoid counterfeit risks.

Selection Notes

Select this component when a single-channel high-power solution is required without complex external biasing networks. The absence of bootstrap and Boucherot cell requirements simplifies PCB layout. Consider the 3V to 18V input range for flexible power supply designs in consumer electronics.

Part Context

This part belongs to the TDA7266 series of audio amplifiers by STMicroelectronics. While the base series includes dual bridge versions like the TDA7266D, the TDA7266M specifically denotes the mono bridge variant. It shares core protection features and low-component design philosophy with its siblings but differs in channel configuration.
