1 UNISONIC TECHNOLOGIES CO., 12 BTL OR 2 6 STEREO CAR RADIO POER AMPLIFIER DESCRIPTION The UTC TDA1519B is an integrated class B dual output amplifier. It contains two identical amplifiers with differential stages. The gain of each amplifier is fixed at. The device is primarily developed for car radio application. FEATURES * Requires very few external components for BridgeTied Load (BTL) operation * Stereo or BTL application * High output power * Low standby current (<0μA) * Low mute/standby ing current * Load dump protection * AC and DC shortcircuit safe to and Vp * Thermally protected HSIP9 *Pbfree plating product number:tda1519bl PIN DESCRIPTION PIN No. PIN NAME DESCRIPTION 1 NINV Noninverting 2 GND1 Ground 1(sigal) 3 RR Supply Voltage Ripple Rejection OUT1 Output 1 5 GND2 Ground 2(substrate) 6 OUT2 Output 2 7 Vp Positive Supply Voltage M/SS Mute/Standby Switch 9 INV Inverting Input ORDERING INFORMATION Ordering Number Normal Lead Free Plating Package Packing TDA1519BH09T TDA1519BLH09T HSIP9 Tube 1 Copyright 2005 Unisonic Technologies Co.,
