TBA820M

Overview

The TBA820M is a monolithic integrated audio amplifier manufactured by STMicroelectronics, housed in an 8-lead MiniDIP plastic package. Designed as a low-frequency Class B power amplifier, it operates on a supply voltage range of 3V to 16V. Key electrical specifications include a maximum supply voltage of 16V, a quiescent output voltage of 4.5V (typical), and a quiescent drain current of 12mA (typical). The device delivers an output power of 2W at 12V into an 8Ω load, 1.6W at 9V into a 4Ω load, and 1.2W at 9V into an 8Ω load. It features a junction temperature range of -40°C to 150°C and a thermal resistance of 100°C/W.

Feature Summary

Operates with a minimum working supply voltage of 3V
Eliminates crossover distortion for cleaner audio reproduction
Provides good ripple rejection capabilities
Requires a minimal number of external components

Applications

Portable radios
Cassette recorders
Cassette players

Procurement Notes

Verify component authenticity through authorized channels due to the part's discontinued status. Confirm that the received unit matches the specific 8-lead MiniDIP package outline and pin configuration detailed in the datasheet. Ensure storage conditions remain within the specified temperature limits to maintain integrity before installation.

Selection Notes

Select this component for designs requiring a simple, low-voltage Class B audio solution. It is suitable for applications where low quiescent current and minimal external circuitry are priorities. Consider the 8-lead DIP package constraints and the specific power delivery requirements relative to the available supply voltage and load impedance.

Part Context

The TBA820M belongs to the TBA820 family of audio amplifiers produced by STMicroelectronics. It is specifically engineered for portable consumer electronics that require reliable audio amplification within a compact form factor. The device integrates the necessary circuitry for Class B operation into a single monolithic chip.
