AN7161N

Overview

The Panasonic AN7161N is a monolithic integrated circuit designed as a BTL high-power audio amplifier with an integrated headphone amplifier. It supports applications in Hi-Fi systems, car stereos, and TV sound multiplex outputs. The device combines power amplification capabilities for speakers with dedicated drive circuits for headphones, offering a compact solution for audio output stages.

Feature Summary

• Integrates bridge-tied-load (BTL) audio power amplifier functionality
• Includes built-in headphone amplifier section
• Monolithic IC construction for simplified design

Applications

• Hi-Fi audio systems
• Car stereo units
• TV sound multiplex outputs

Procurement Notes

Verify the exact suffix (e.g., NFP) against current Panasonic Semiconductor documentation to ensure pinout and package compatibility. Confirm availability status as legacy semiconductor parts may have limited production runs or obsolescence notices.

Selection Notes

Select this component when a combined speaker and headphone amplifier solution is required in a single package. Ensure the application voltage and thermal requirements align with the BTL amplifier specifications provided in the official datasheet.

Part Context

This part belongs to Panasonic's analog semiconductor lineup, specifically within the audio amplifier category. It serves as a specialized solution for consumer electronics requiring multi-channel audio output without separate discrete components.

Replacement Considerations

Cross-reference with similar BTL audio power amplifiers such as the Toshiba TA7250BP or Fujitsu MB3735 if pin-to-pin compatibility is not guaranteed. Verify functional equivalence for both speaker and headphone sections.
