TDA7384 Datasheet

4 x 46 W quad bridge car radio amplifier


The TDA7384 is an AB class audio power amplifier, packaged in Flexiwatt 25 and designed for high end car radio applications.Based on a fully complementary PNP/NPN configuration, the TDA7384A allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced boundary components allows very compact sets. TDA7384 Applications • High output power capability: – 4 x 46 W / 4 Ω max. – 4 x 27 W / 4 Ω @ 14.4 V, 1 kHz, 10 %• Low distortion• Low output noise• Standby function• Mute function• Automute at min. supply voltage detection• Low external component count: – Internally fixed gain (26 dB) – No external compensation – No bootstrap capacitors• Protections: – 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 – ESD
