TITPA6132A2RTER
Overview
The TPA6132A2 is a stereo Class AB DirectPath headphone amplifier designed to eliminate the need for large DC-blocking output capacitors. It operates from a supply voltage of 2.3V to 5.5V and provides a constant maximum output power of 25mW per channel into 16-ohm loads. The device features integrated click-and-pop suppression and high RF noise immunity for clean audio performance in mobile environments.
Why Choose This Part
The DirectPath architecture simplifies PCB layout and reduces BOM cost by removing the need for external DC-blocking capacitors. Engineers can select between four fixed gain settings (-6, 0, 3, or 6 dB) using internal resistors, while the integrated pop-suppression circuitry ensures a quiet power-up and power-down sequence.
Applications
Key Specifications
Getting Started
To evaluate the chip, TI offers the TPA6132A2EVM evaluation module which provides easy access to all pins and gain configurations. Ensure the thermal pad of the 16-WQFN package is soldered to a ground plane for optimal heat dissipation and performance. Use 1uF ceramic capacitors for supply bypassing and input coupling as recommended in the datasheet.
