Overview
The TDF8599TH/N2,518, produced by NXP USA Inc., is a high-efficiency, I²C-bus controlled dual-channel class-D power amplifier. This device is designed for car audio applications and features a Bridge-Tied Load (BTL) configuration with an NDMOST-NDMOST output stage based on SOI BCDMOS technology. The amplifier is known for its low power dissipation, allowing it to operate with a smaller heat sink compared to standard class-AB amplifiers. It can operate in both non-I²C-bus mode and I²C-bus mode, enabling features like DC load detection and fault condition reporting through the I²C interface.
