Overview
The AN5274 is a monolithic dual-channel SEPP audio power amplifier IC designed for stereo TV applications. It delivers 4.0 W output into an 8 Ω load at 18 V supply. The device operates within a VCC range of 14.2 V to 27.5 V. Key electrical characteristics include a voltage gain of 30 dB, quiescent current of 25 mA, and ripple rejection of 35 dB. It features built-in DC volume control, mute functionality, thermal protection, and over-current protection.
Feature Summary
- Integrated DC volume control and mute circuit for system management
- Built-in thermal and over-current protection circuits for reliability
- Enhanced ripple rejection performance compared to previous series models
Applications
- Stereo audio amplification in television sets
- Consumer audio equipment requiring integrated volume and mute control
Procurement Notes
Verify the specific package type HSIP012-P-0000A matches your board layout requirements. Confirm that the operating voltage range of 14.2 V to 27.5 V aligns with your system's power supply design. Ensure proper heat sinking is planned, as thermal dissipation depends on ambient temperature and load conditions.
Selection Notes
Select this component for stereo TV applications requiring a single-chip solution with integrated volume and mute controls. Consider the 4.0 W output capability into 8 Ω loads when designing speaker interfaces. Evaluate the need for external heatsinks based on maximum power dissipation requirements and ambient operating temperatures.
Part Context
The AN5274 belongs to Panasonic's ICs for Audio Common Use series. It serves as a successor or alternative to models like the AN5273, offering improved ripple rejection. The device is part of a family of audio power amplifiers designed for consumer electronics, specifically targeting cost-effective and space-constrained applications like televisions.
Replacement Considerations
The AN5273 is noted for having lower ripple rejection compared to the AN5274. Other similar parts in the series include the AN5270, AN5272, AN5275, and AN5276, which vary in channel count and power output specifications.
