The TDA7384A 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.

High output power capability:

• 4 x 46 W / 4 Ω max.
• 4 x 27 W / 4 Ω @ 14.4 V, 1 kHz, 10 %
