TDA7365 2 x 6W CAR RADIO AMPLIFIER PLUS SOLID STATE SWITCH ADVANCE DATA OUTPUT POWER 2x6W/4Ω @14.4V, 1KHz, 10% SOLID STATE POWER SWITCH INCLUDED (1A @ VDROP = 0.8V Typ.) MINIMUM EXTERNAL COMPONENT COUNT - INTERNALLY FIXED GAIN (40dB) - NO BOOTSTRAP CAPACITORS - NO EXTERNAL COMPENSATION ST-BY FUNCTION (CMOS COMPATIBLE) MUTE FUNCTION (CMOS COMPATIBLE) NO AUDIBLE POP DURING MUTE/ST-BY OPERATIONS LOW SUPPLY SELF MUTING PROTECTIONS AC AUDIO OUTPUTS SHORT CIRCUIT TO GND DC AUDIO OUTPUTS SHORT CIRCUIT TO GND AND TO VS AT POWER ON SWITCH OUTPUT INTERNAL CURRENT LIMITATION OVERRATING CHIP TEMPERATURE WITH SOFT THERMAL LIMITER LOAD DUMP FORTUITOUS OPEN GND MULTIWATT15 ORDERING NUMBER: TDA7365 REVERSE BATTERY ESD DESCRIPTION The TDA7365 is a new technology Dual Audio Amplifier in Multiwatt15 package especially designed for stereo car radio applications. Thanks to the fully complementary output configuration the TDA7365 delivers a rail to rail voltage swing with no need of boostrap capacitors It includes a solid state switch, enabled by a ST-BY function common to the audio section, suitable for supplying both the signal processing part of the car radio set and the lamps. As a results the power-on operation is simplified, thereby saving cost and space in the whole power section.
