TITPA3116D2EVM

Overview

The TPA3116D2EVM is an evaluation module for the TPA3116D2 Class D stereo audio amplifier, capable of driving 50W per channel into 4-Ohm loads. This board operates over a wide supply range of 4.5V to 26V and features SpeakerGuard protection to prevent output clipping and damage. It is designed to demonstrate high-efficiency audio performance with AM avoidance and advanced oscillator/PLL circuitry.

Why Choose This Part

The board features advanced AM avoidance circuitry which allows the amplifier to synchronize its switching frequency to prevent interference with AM radio bands. It utilizes the TPA3116D2 IC's high efficiency to eliminate the need for large heatsinks while providing up to 100W of total stereo power. Additionally, the integrated SpeakerGuard system includes an adjustable power limiter to protect connected transducers.

Applications

Getting Started

To begin evaluation, connect a DC power supply between 4.5V and 26V to the power terminals and an audio source via the RCA input jacks. Use the onboard jumpers to configure the gain settings and the AM avoidance mode according to your system requirements. Ensure speakers with a minimum 4-Ohm impedance are connected before applying power to prevent overcurrent conditions.
