TDF8597 - Class-D Power Amplifier

General Description

The TDF8597 is a dual Bridge-Tied Load (BTL) car audio amplifier comprising an NDMOST-NDMOST output stage based on SOI BCDMOS technology.

The TDF8597 fully supports start/stop systems as it can operate at a battery voltage as low as 6 V.

The TDF8597 can be controlled with or without I2C.

Key Features

  • High-efficiency.
  • Low quiescent current.
  • Operating voltage from 6 V to 24 V.
  • Start/Stop ready: continues to operate without audible disturbance during engine start at a battery voltage as low as 6 V.
  • 4  or 2  capable stereo BTL channels or 1  capable mono BTL channel.
  • Differential inputs.
  • Fast-mode I2C-bus.
  • I2C-bus mode with 6 I2C-bus addresses or non-I2C-bus mode operation.
  • Clip detect selectable at 0.2 % or 10 % THD.
  • Independent short-circui.

TDF8597 I2C-bus controlled dual channel 43 W/2 , single channel 85 W/1  class-D power amplifier with full diagnostics Rev. 1 — 17 November 2011 Preliminary short data sheet 1. General description The TDF8597 is a dual Bridge-Tied Load (BTL) car audio amplifier comprising an NDMOST-NDMOST output stage based on SOI BCDMOS technology. The TDF8597 fully supports start/stop systems as it can operate at a battery voltage as low as 6 V. The TDF8597 can be controlled with or without I2C. I2C allows control of load detection results and fault conditions to be read. The TDF8597 is a high efficiency class-D amplifier with low dissipation. Due to the low dissipation, the device can be used with a smaller heat sink than standard class AB amplifiers.
