TDA7370BV

Overview

The TDA7370BV is a Class AB audio amplifier IC manufactured by STMicroelectronics, housed in a 15-Multiwatt package. It supports 2-channel stereo or 4-channel quad configurations with a supply voltage range of 8V to 18V. Maximum output power reaches 20W per channel into 4-ohm loads for stereo operation and 6.5W per channel for quad setups. The device operates within a junction temperature range of -40°C to 150°C.

Feature Summary

• Features fully complementary PNP/NPN output stage configuration enabling rail-to-rail voltage swing without bootstrap capacitors.
• Includes differential input pairs accepting single-ended or differential signals for high noise immunity.
• Integrates mute control to suppress pop-on/off transients and standby function to reduce power switch costs.
• Contains on-board programmable distortion detector for compression facility when overdriven.

Applications

• Car radio applications
• Car booster systems

Procurement Notes

Verify component authenticity through authorized channels as the TDA7370BV is marked obsolete. Confirm RoHS3 compliance and check for valid replacement parts like the TDA7376B if current production is required. Ensure the Multiwatt-15 package matches design constraints before procurement.

Selection Notes

Select this component for automotive audio designs requiring robust protection features including short circuit, thermal limiting, and load dump voltage handling. The internal fixed gain of 26 dB simplifies circuit design. Verify compatibility with 14.4V automotive electrical systems and ensure adequate heat sinking for the specified power outputs.
