TDA8586

INTEGRATED CIRCUITS DATA SHEET TDA8586 Power amplifier with load detection and auto BTL/SE selection Preliminary specification Supersedes data of 1998 May 25 File under Integrated Circuits, IC01 1999 Apr 08 Philips Semiconductors Preliminary specification Power amplifier with load detection and auto BTL/SE selection FEATURES General Operating voltage from 8 to 18 V Low distortion Few external components, fixed gain Automatic mode selection (SE or BTL) depending on connected ‘rear’ loads Can be used as a stereo amplifier in Bridge-Tied Load (BTL) or quad Single-Ended (SE) amplifiers Single-ended mode without loudspeaker capacitor Soft clipping, to guarantee good clip behaviour with inductive loads Mute and standby mode with one-pin operation Diagnostic information for Dynamic Distortion Detector (DDD), high temperature (140 °C) mode of operation and short-circuit No switch-on/off plops when switching between standby and mute and from mute to on Load detection on ‘rear’ channels when switching from standby to mute Fast mute on supply voltage drops (low VP mute). Protection 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 Overvoltage protection.
