TITPA3116D2DADR
Overview
The TPA3116D2DADR is a high-efficiency, Class-D stereo audio amplifier capable of driving up to 50W per channel into 4-Ohm loads. Operating from a wide supply range of 4.5V to 26V, it integrates advanced self-protection features including DC detection and short-circuit protection. It is designed to minimize external component counts while providing high-quality audio reproduction through differential inputs and multiple switching frequencies.
Why Choose This Part
The device features a programmable power limit and multiple switching frequencies to optimize EMI performance and avoid AM radio interference. Its differential inputs provide excellent noise rejection, while the integrated protection circuits ensure system reliability against overvoltage, undervoltage, and thermal overloads.
Applications
Key Specifications
Getting Started
Engineering evaluation can be performed using the TPA3116D2EVM evaluation module, which provides a reference layout for thermal management via the HTSSOP PowerPAD. Design focus should be placed on proper decoupling of the single power supply and ensuring the exposed thermal pad is soldered to a sufficient ground plane for heat dissipation.
