TITPA2012D2RTJR
Overview
The TPA2012D2RTJR is a stereo, filter-less Class-D audio power amplifier capable of delivering up to 2.1W per channel into a 4-ohm load. Operating from a supply voltage of 2.5V to 5.5V, it is designed for high efficiency and minimal external component count in compact electronic designs. The device features differential inputs to improve noise rejection and integrated protection circuitry.
Why Choose This Part
This amplifier eliminates the need for bulky LC output filters, reducing overall system cost and board space. It features an extremely low shutdown current of 1.5uA and high efficiency, which significantly extends battery life in portable applications. Integrated thermal and short-circuit protection ensure device reliability under varying load conditions.
Applications
Key Specifications
Getting Started
To evaluate this part, use the TPA2012D2EVM evaluation module which provides a complete reference layout and terminal blocks for quick testing. Ensure that the 20-WFQFN exposed pad is properly soldered to a grounded thermal plane to manage heat dissipation at high power levels. Place decoupling capacitors as close to the VDD pins as possible to maintain signal integrity.
