TDA8587J - 4 x 25 W BTL power amplifier

Description

The TDA8587J is a combination of a quad Bridge-Tied Load (BTL) power amplifier, a multiple voltage regulator and a power switch.

Several protections and diagnostic options (e.g.

DIAG, WARN) are incorporated in this design.

TDA8587J Rev. 01 — 23 December 2004 www.DataSheet4U.com 4 × 25 W BTL power amplifier and multiple voltage regulator with power switch Preliminary data sheet 1. General description The TDA8587J is a combination of a quad Bridge-Tied Load (BTL) power amplifier, a multiple voltage regulator and a power switch. Several protections and diagnostic options (e.g. DIAG, WARN) are incorporated in this design. This device is primarily developed to cover the complete power supply and audio amplifier requirements in low and mid-end car radio applications. The switchable regulators (regulators 1, 3 and 4) are intended to be used as supplies for the tuner, logic, digital or analog sound processor and CD / tape control.
