Overview
The AN17820B is a monolithic silicon bipolar integrated circuit designed as a dual-channel BTL audio power amplifier. It delivers 7.5 W per channel into an 8 Ω load at VCC = 15 V with THD = 10%. The device operates within a supply voltage range of 5.0 V to 18.0 V and features built-in standby and volume control circuits. It utilizes a 12-pin plastic single inline package (HSIP012-P-0000L) with an integrated heat sink, suitable for stereo operation in television applications.
Feature Summary
- Built-in standby circuit for power management
- Integrated volume control functionality
- Dual-channel bridge-tied-load (BTL) architecture
Applications
- Low frequency amplifiers
- Television audio systems
Procurement Notes
Verify the current lifecycle status on Panasonic's official semiconductor website before design finalization. Confirm that the HSIP012-P-0000L package matches your PCB footprint requirements. Ensure thermal management designs account for the specified power dissipation limits at maximum operating temperatures.
Selection Notes
Select this component for stereo audio applications requiring integrated gain and standby controls. Verify that the 5.0 V to 18.0 V supply range aligns with system power rails. Consider the SIP package with heat sink for thermal efficiency in compact enclosures without external heatsinks.
Part Context
This part belongs to Panasonic's discrete semiconductor and integrated circuit portfolio. It is specifically engineered for consumer electronics audio stages. The device integrates pre-amplifier and driver circuits within a single silicon monolithic structure.
Replacement Considerations
Consult Panasonic's official documentation for verified substitute part numbers or updated series replacements. Do not assume pin-compatible alternatives without explicit manufacturer confirmation.
FAQ
How is the standby function controlled?
The standby pin activates when pulled to 0 V and deactivates at 5 V. A delay circuit using a resistor and capacitor is recommended to prevent pop noise during transitions.
Is an output Zobel network required?
No, the device is designed for stable operation without an output Zobel network. However, one may be added optionally to ensure stability with specific speaker types or PCB layouts.
