TITPA3111D1PWPR
Overview
The TPA3111D1PWPR is a 10W mono Class D audio power amplifier designed to drive a single bridge-tied load (BTL) speaker. It operates over a wide voltage range of 8V to 26V and features SpeakerGuard technology to protect against DC offsets and over-power conditions. This IC is optimized for filter-free operation, allowing for reduced component count and board space in cost-sensitive audio designs.
Why Choose This Part
The device features a flow-through pinout that simplifies PCB layout and minimizes parasitic interference. It includes four selectable fixed-gain settings to accommodate different input signal levels without external resistors. Its SpeakerGuard protection system includes an adjustable power limiter, providing robust protection for low-wattage drivers.
Applications
Key Specifications
Getting Started
Designers should prioritize the thermal pad connection to a large PCB ground plane to manage heat dissipation effectively. Evaluation can be performed using the TPA3111D1EVM module, which provides access to the gain pins and the adjustable power limit (PLIMIT) functionality. Ensure high-quality decoupling capacitors are placed as close to the VCC pins as possible to minimize EMI.
