TDF8599B Datasheet Single Channel 85 W/1 W Class-d Power Amplifier

Manufacturer: NXP Semiconductors

Overview: TDF8599B I2C-bus controlled dual channel 43 W/4 Ω, single channel 85 W/1 Ω class-D power amplifier with load diagnostics Rev. 01 — 29 July 2009 Product data sheet 1.

General Description

The TDF8599B is a dual Bridge-Tied Load (BTL) car audio amplifier prising an NDMOST-NDMOST output stage based on SOI BCDMOS technology.

Low power dissipation enables the TDF8599B high-efficiency, class-D amplifier to be used with a smaller heat sink than those normally used with standard class-AB amplifiers.
