Product Introduction

Overview

The TDA7376PDTR is a dual bridge audio amplifier produced by STMicroelectronics, designed specifically for car radio applications. This component is part of the TDA7376PD series and is packaged in the PowerSO36 format. It features a fully complementary PNP/NPN output stage configuration, which enables a rail-to-rail voltage swing without the need for bootstrap capacitors. The amplifier is known for its high output power capability, differential inputs, and minimal external component requirements, making it suitable for both car radio and car booster applications.

  • 2 Ω driving capability.
  • Differential inputs accepting single-ended or differential input signals.
  • Internally fixed gain of 26 dB.
  • Mute function (CMOS compatible) with no audible pop during mute and standby operations.
  • Standby function that de-biases the amplifiers.
  • Programmable clipping distortion detector with adjustable threshold.
  • Comprehensive protection features including short circuit, overrating chip temperature, load dump voltage, fortuitous open ground, loudspeaker DC current, and ESD protection.

Applications

The TDA7376PDTR is primarily designed for car radio applications, but it is also suitable for car booster applications due to its high noise immunity and robust protection features.

Q & A

  1. What is the maximum output power of the TDA7376PDTR?

    The maximum output power is up to 2 x 40 W max./4 Ω and 2 x 35 W/4 Ω EIAJ.

  2. What is the supply voltage range for the TDA7376PDTR?

    The supply voltage range is from 8 to 18 V.

  3. Does the TDA7376PDTR have a mute function?
  4. What kind of protection features does the TDA7376PDTR have?
