TDA2822M

Overview

The TDA2822M is a monolithic integrated circuit housed in an 8-lead MiniDIP package, designed as a dual audio power amplifier. It operates with a supply voltage range from 1.8 V to 15 V and delivers 1 W of output power into a 32 Ohm load. The device features Class-AB topology with 0.2% THD+N, 39 dB gain, and 1 A output current capability. It supports single-supply operation and functions within a temperature range of -40°C to +150°C.

Feature Summary

• Dual low-voltage power amplifier architecture
• Low crossover distortion performance
• Low quiescent current consumption

Applications

• Portable cassette players
• Portable radios
• CD players

Procurement Notes

Verify the specific suffix 'M' corresponds to the MiniDIP8 package variant rather than other packaging options like SOIC or DIP. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure input signal levels remain within specified limits to prevent thermal overload during high-power operation.

Selection Notes

Select this component for stereo audio applications requiring low-voltage operation and minimal external components. The dual-channel configuration simplifies board layout compared to single-channel alternatives. Verify that the required output power aligns with the 1 W specification at the target load impedance.

Part Context

This part belongs to the TDA2822 series of dual audio power amplifiers manufactured by STMicroelectronics. The series is engineered for portable consumer electronics where space and power efficiency are critical constraints. The M suffix specifically denotes the MiniDIP8 physical package format.
