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
