Integrated Circuit
20W Bridge Booster for Car Radio
Description:
The NTE1396 is a Class B dual audio power amplifier specifically designed for car radio applications.
Power booster amplifiers are easily designed using this device that provides a high current capability
(up to 3.5A) and that can drive very low impedance loads obtaining an output power of more than 20W.
The NTE1396 has high reliability and guarantees complete safety during operation due to protection
against:
D Output DC and AC Short Circuit to GND or Across the Head
D Overrating Chip Temperature (+150°C)
D Polarity Inversion
D Load Dump Voltage Surge
D Fortuitous Open GND
D Very Inductive Loads
