Multi-purpose power amplifier

Preliminary specification

TDA8580J

FEATURES

General

• Supply voltage range from 8 to 24 V

• Low distortion

• Few external components, fixed gain

• High output power

• Can be used as a stereo amplifier in Bridge-Tied Load

(BTL) or quad Single-Ended (SE) amplifiers

• Single-ended mode without loudspeaker capacitor

• Mute and standby mode with one- or two-pin operation

• Diagnostic information for Dynamic Distortion Detector

(DDD), high temperature (145 °C) and short-circuit

• No switch on/off plops when switching between standby

and mute or mute and on; an external RC-network is

prescribed to ensure plop-free operation

• Low offset variation at outputs between mute and on

• Fast mute on supply voltage drops.

Protection

• Short-circuit proof to ground, positive supply voltage and

across load; the supply voltage ranges where the

different short circuit conditions are guaranteed are

given in Chapter “Limiting values”

• ESD protected on all pins

• Thermal protection against temperatures exceeding

150 °C.

GENERAL DESCRIPTION

The TDA8580J is a stereo Bridge-Tied Load (BTL) or a

quad Single-Ended (SE) amplifier that operates over a

wide supply voltage range from 8 to 24 V. This makes it

suitable for applications such as television, home-sound

systems and active speakers.

Because of an internal voltage buffer, this device can be

used without a capacitor connected in series with the load

(SE application). A combined BTL and 2 × SE application

can also be configured (one chip stereo and subwoofer

application).
