TDA8581

INTEGRATED CIRCUITS DATA SHEET TDA8581 Multi-purpose high-gain power amplifier Preliminary specification File under Integrated Circuits, IC01 1998 May 27 Philips Semiconductors Preliminary specification Multi-purpose high-gain power amplifier 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. 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. ORDERING INFORMATION TYPE NUMBER TDA8581 PACKAGE NAME DBS17P DESCRIPTION plastic DIL-bent-SIL power package; 17 leads (lead length 12 mm) GENERAL DESCRIPTION TDA8581 The TDA8581 is a stereo bridge-tied load (BTL) or a quad single-ended amplifier that operates over ...
