TDA7562 STMicroelectronics

TDA7562 MULTIFUNCTION QUAD POWER AMPLIFIER WITH BUILT-IN DIAGNOSTICS FEATURES DMOS POWER OUTPUT MULTIPOWER BCD TECHNOLOGY HIGH OUTPUT POWER CAPABILITY 4x25W/ 4 14.4V, 1KHZ, 10% THD, 4x35W EIAJ MOSFET OUTPUT POWER STAGE MAX. OUTPUT POWER 4x60W/2 2 FULL I C BUS DRIVING: ST-BY INDEPENDENT FRONT/REAR SOFT PLAY/ MUTE SELECTABLE GAIN 30dB - 16dB (FOR LOW NOISE LINE OUTPUT FUNCTION) FLEXIWATT27 (Vertical) 2 I C BUS DIGITAL DIAGNOSTICS FULL FAULT PROTECTION DC OFFSET DETECTION Bridge type of car radio amplifier in Flexiwatt27V FOUR INDEPENDENT SHORT CIRCUIT package specially intended for car radio applica- PROTECTION tions. Thanks to the DMOS output stage the CLIPPING DETECTOR PIN WITH TDA7562 has a very low distortion allowing a clear SELECTABLE THRESHOLD (2%/10%) powerful sound. This device is equipped with a full ST-BY/MUTE PIN diagnostics array that communicates the status of ESD PROTECTION 2 each speaker through the I C bus.The possibility to control the configuration and the behaviour of 2 DESCRIPTION the device by means of the I C bus makes The TDA7562 is a new BCD technology Quad TDA7562 a very flexible machine.
