Overview
The TDA7376PDTR is a dual bridge audio amplifier in PowerSO-36 package designed for car radio applications. It delivers up to 40W per channel into 4Ω loads and features differential inputs for high noise immunity. Key electrical parameters include an internal fixed gain of 26 dB, supply voltage range of 8V to 18V, and operating temperature from -40°C to +150°C TJ. It includes mute, standby, and programmable clipping detection functions.
Feature Summary
- Fully complementary PNP/NPN output stage configuration enabling rail-to-rail voltage swing without bootstrap capacitors.
- Differential input pairs accept single-ended or differential signals to guarantee high noise immunity.
- On-board programmable distortion detector allows compression facility whenever the amplifier is overdriven.
- Integrated protections against short circuits, thermal overload, load dump voltage, and fortuitous open ground.
Applications
- Car radio main amplifiers
- Car booster systems
- Automotive audio power stages
Procurement Notes
Verify component authenticity through authorized STMicroelectronics distributors. Confirm package integrity as the device is surface-mount. Check datasheet revisions for any design changes. Ensure ESD handling protocols are followed during assembly due to CMOS-compatible control inputs.
Selection Notes
Select this part for automotive stereo applications requiring high output power with minimal external components. The PowerSO-36 package offers thermal efficiency. Verify compatibility with 12V vehicle electrical systems within the specified voltage range. Consider the obsolete status when planning long-term production.
Part Context
This component belongs to the TDA7376 family of Class AB audio amplifiers. It is specifically engineered for automotive environments, offering robust protection features against harsh electrical conditions. The PD suffix indicates the PowerSO-36 surface-mount package variant.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. The product status is listed as Obsolete. Designers should consult STMicroelectronics for current alternatives or verify pin-compatible successors independently.
