TITPA3110D2PWP
Overview
The TPA3110D2PWP is a 15W per channel stereo Class-D audio power amplifier designed to drive speakers without the need for a bulky external LC output filter. It operates from a wide supply voltage range of 8V to 26V and features high-efficiency operation to minimize heat sink requirements. Integrated SpeakerGuard technology provides an adjustable power limiter and DC protection to prevent damage to connected transducers.
Why Choose This Part
The device features filter-free operation which reduces board space and BOM cost by eliminating the output LC filter. It includes robust protection circuitry such as pin-to-pin short circuit and thermal protection with an auto-recovery option. Differential inputs and a high PSRR of 70dB help to minimize noise and simplify board layout in complex systems.
Applications
Key Specifications
Getting Started
Start by consulting the TPA3110D2EVM evaluation module documentation for recommended PCB layout patterns, specifically focusing on the thermal pad for the HTSSOP package. Ensure power supply decoupling capacitors are placed as close to the VCC pins as possible to handle the high-speed switching transients of the Class-D stage. Set the four fixed gain levels using the GAIN0 and GAIN1 pins to match your input source signal level.
