The TDA7386 is a new technology class AB audio power amplifier in Flexiwatt 25 package designed for high end car radio applications.
Thanks to the fully complementary PNP/NPN output configuration the TDA7386 allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced components count allows very compact sets.
■ High output power capability:
■ 4 x 45W/4Ω max.
■ 4 x 28W/4Ω @ 14.4V, 1KHz, 10%
■ 4 x 24W/4Ω @ 13.2V, 1KHz, 10%
■ Low distortion
■ Low output noise
■ St-by function
■ Mute function
■ Automute at min. supply voltage detection
■ Low external component count:
– Internally fixed gain (26dB)
– No external compensation
– No bootstrap capacitors
■ Output short circuit to GND, to VS, across the load
■ Very inductive loads
■ Overrating chip temperature with soft thermal limiter
■ Load dump voltage
■ Fortuitous open GND
■ Reversed battery
