STMicroelectronics | E-TDA7384A

The E-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.

Features:

• High output power capability:
  • 4 x 42 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
