The TPA6120A2 is a high fidelity audio amplifier built on a current-feedback architecture. This high bandwidth, extremely low noise device is ideal for high performance equipment. Its better than 120 dB of dynamic range exceeds the capabilities of the human ear, ensuring that nothing audible is lost due to the amplifier. The solid design and performance of the TPA6120A2 ensures that music, not the amplifier, is heard.
The TPA6120A2 is a high‑fidelity, current‑feedback headphone driver offering over 120 dB dynamic range, low THD+N (0.00014 %), and a slew rate of 1300 V/µs. It supports ±5 V to ±15 V supplies and delivers 80 mW into 600 Ω from a ±12 V supply, making it suitable for premium audio equipment.
The datasheet details absolute maximum ratings, recommended operating conditions, pin functions, and typical performance graphs such as THD+N versus frequency, output power, and supply‑voltage rejection. It also includes package information for the thermally‑enhanced DWP package and notes on short‑circuit and thermal protection.
