PA7375

UNISONIC TECHNOLOGIES CO., LTD PA7375 LINEAR INTEGRATED CIRCUIT 2 x 35W DUAL/QUAD POWER AMPLIFIER FOR CAR RADIO „ DESCRIPTION The UTC PA7375 is a class AB car radio amplifier for car radio, it can work either in dual bridge or quad single ended configuration. The exclusive fully complementary structure of the output stage and the internally fixed gain guarantees the highest possible power performances with few external components. The on-board clip detector simplifies gain compression operation. The fault diagnostics makes it possible to detect mistakes during car radio set assembly and wiring in the car. „ FEATURES * High output power capability: – 2 x 40W Max. / 4Ω – 2 x 25W / 4Ω@14.4V, 1KHz, 10% – 2 x 35W / 4Ω EIAJ – 4 x 7 W / 4Ω@14.4V, 1KHz, 10% – 4 x 12W / 2Ω@14.4V, 1KHz, 10% * Minimum external components: – No bootstrap capacitors – No Boucherot cells – Internally fixed gain (26dB BTL) * Stand-by function (CMOS compatible) * No audible pop during st-by operations * Diagnostics facility for: – Clipping – Out to GND short – Out to VS short – Soft short at turn-on – Thermal shutdown proximity Lead-free: PA7375L Halogen-free: PA7375G „ PROTECTIONS * Output AC/DC short circuit – to GND – to VS – across the load * Soft short at turn-on * Overrating chip temperature with soft thermal limiter * Load dump voltages urge * Very inductive loads * Fortuitous open GND * Reversed battery * ESD „ ORDERING INFORMATION Normal PA7375-J15-D-T Ordering Number Lead Free Plating PA...
