Overview
The PAM8106TVR is a stereo Class-D audio power amplifier manufactured by Diodes Incorporated, housed in a W-QFN5050-32 package. It operates on a supply voltage ranging from 4.5V to 15V and delivers up to 10W per channel into an 8Ω load with a 12V supply. The device achieves over 92% efficiency and incorporates Spread-Spectrum Modulation (SSM) for EMI suppression. Key electrical parameters include a 95dB SNR, -70dB PSRR, and a closed-loop gain of 32dB.
Feature Summary
- Integrates Non-Clipping Power Limit (NCPL) technology to adjust gain and prevent output signal clipping caused by over-level input signals.
- Utilizes Spread-Spectrum Modulation (SSM) to suppress electromagnetic interference, allowing the use of inexpensive ferrite bead filters instead of complex inductors.
- Provides comprehensive fault protection including short-circuit protection, thermal shutdown, undervoltage lockout, and DC input protection.
Applications
- Flat Monitor & LCD TVs
- Multi-Media Speaker Systems
- DVD Players and Game Machines
- Boom Boxes and Consumer Electronics
- Musical Instruments
Procurement Notes
Verify the specific ordering suffix 'TVR' corresponds to the Tape & Reel shipping configuration containing 3,000 units per reel. Confirm that the component marking matches the internal code format described in the datasheet. Ensure compliance with RoHS directives and Halogen-free requirements as specified by the manufacturer's definitions for this product line.
Selection Notes
Select this component for applications requiring high-efficiency stereo amplification without heat sinks. The device supports both differential and single-ended audio inputs. Designers must account for the 32dB fixed closed-loop gain and ensure adequate decoupling capacitors are placed near the AVCC and PVCC pins to maintain optimal performance and stability.
Part Context
This part belongs to the PAM8106 series of Class-D audio amplifiers. It is designed to replace traditional linear amplifiers in portable and consumer electronics where size constraints and thermal management are critical. The W-QFN5050-32 package facilitates compact PCB layouts while providing necessary thermal dissipation through the exposed pad.
Replacement Considerations
No public confirmed substitute part numbers are documented in the provided datasheet.
FAQ
How is the Spread Spectrum Modulation (SSM) feature controlled?
SSM can be enabled by setting the SSMCTL pin to a Logic-Low or left floating after power-up due to an embedded pull-up resistor. It is disabled by applying a Logic-High to the SSMCTL pin.
What is the behavior of the Short-Circuit Protection?
Upon detecting a short circuit on the outputs, the drive is immediately disabled. This is a latched fault that requires cycling the SD pin from logic low to logic high to reset and restore normal operation.
