TDA 7388 IC - 4 Channel Audio Amplifier TDA7388

Product Overview

The TDA7388 is a four-channel, class AB power amplifier circuit designed for high-end automotive audio systems. It features a BTL (Bridge-Tied Load) output configuration and is packaged in an FZIP25 format.

Core Specifications

• Manufacturer: JSMSEMI (杰盛微半导体).

• Output Power: Capable of maximum power output up to 4 x 41 W into a 4 Ohm load (at 14.4 V, 1 kHz, 10 percent THD).

• Gain: The device features a fixed internal gain of 26 dB (BTL).

• Supply Voltage:

  • Operating voltage: Up to 18 V.

  • DC power voltage: Up to 28 V.

  • Peak voltage (t=50ms): Up to 50 V.

• Input Impedance: 100 kOhm (typical).

Key Features

• Control Functions: Includes both stand-by and mute functions.

• Protection Circuitry:

  • Output Short-Circuit Protection: Protects against short circuits to ground or the power supply, and load short circuits.

  • Thermal Protection: Integrated temperature protection function.

  • Over-Voltage/Current Protection: Includes over-voltage and over-current protection modules.

  • Automatic Mute: Automatically activates the mute function when the supply voltage is low.

• Design Benefits: Requires few peripheral components and does not require bootstrap capacitors. It is also designed to eliminate audible pop noises during startup.

Applications

• Automotive Audio: Specifically designed for high-end automotive audio systems as a four-channel power amplifier.
