TDA7388A is a new technology class AB audio power amplifier in Flexiwatt27 package designed for high end car radio applications.
The document describes the TDA7388A, a new technology class AB audio power amplifier in a Flexiwatt27 package. It is specifically designed for high-end car radio applications and features a fully complementary PNP/NPN output configuration that allows rail-to-rail output voltage swing without needing bootstrap capacitors.
The device offers high output power capability (4x42W at 14V) with low distortion and noise. Key features include internal gain fixing, clipping detection, offset detection, and various protection mechanisms such as thermal shutdown, short-circuit protection, and load dump voltage protection.
| Output power (4 Ohm) | 4 x 42 W / 4 max. |
|---|---|
| Package type | Flexiwatt27 |
| Operating temperature range | -40 to 105 °C |
The amplifier provides a maximum output of 4 x 42W into a 4 ohm load.
No, it does not require external compensation or bootstrap capacitors due to its internal output configuration.
It includes protection for output short circuits, thermal shutdown, load dump voltage, and reversed battery.
