Identify the Revision: Boards may have slight variations (Rev 1.0, 2.0). Ensure your PDF matches the physical board.

  1. Differential Input Stage: The input stage features a differential amplifier configuration, which provides high common-mode rejection ratio (CMRR) and low noise.
  2. Gain Stage: The gain stage is composed of a high-gain amplifier, which provides a large gain bandwidth product.
  3. Output Stage: The output stage is designed to drive heavy loads, with a high output current capability.
  1. Transistors: The IC features multiple transistors, including power transistors and driver transistors, which work together to amplify the audio signal.
  2. Resistors: A range of resistors are used throughout the circuit, providing voltage division, current limiting, and impedance matching.
  3. Capacitors: Capacitors are used for coupling, filtering, and bypassing, helping to ensure a stable and noise-free operation.
