TDA8571J - 4 x 40 W BTL quad car radio power amplifier

General Description

The TDA8571J is a integrated class-B output amplifier contained in a 23-lead Single-In-Line (SIL) plastic power package.

It contains four amplifiers in a BTL configuration, each with a gain of 34 dB.

The output power is 4 × 40 W (EIAJ) into a 4 Ω load.

The device is

Key Features

  • Requires very few external components.
  • High output power.
  • Low output offset voltage.
  • Fixed gain.
  • Diagnostic facility (distortion, short-circuit and temperature pre-warning).
  • Good ripple rejection.
  • Mode select switch (operating, mute and standby).
  • Load dump protection.
  • Short-circuit safe to ground and to VP and across the load.
  • Low power dissipation in any short-circuit condition.
  • Thermally protect.
