Preliminary specification

TDA8581

FEATURES

General

• High gain

• Operating voltage from 8 to 28 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’ to ‘mute’ and from ‘mute’ to ‘on’

• Low offset variation at outputs between ‘mute’ and ‘on’

• Fast mute on supply voltage drops.

GENERAL DESCRIPTION

The TDA8581 is a stereo bridge-tied load (BTL) or a quad

single-ended amplifier that operates over a wide supply

voltage range from 8 to 28 V. This makes it suitable for

many applications, such as car radios, television and

home-sound systems.

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.

Protection

• Reverse polarity safe (with protection diode added)

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

all pins and across load

• ESD protected on all pins

• Thermal protection against temperatures exceeding

150 °C

• Load dump protection

• Protected against open-circuit ground pins and output

short-circuited to supply ground.
