Overview
The BD78326UEFJ-ME2 is a Class-AB monaural speaker amplifier designed for automotive applications. It delivers an output power of 1.2 W with a gain of 26 dB and a THD+N of 0.05%. Operating within a supply voltage range of 4 V to 5.5 V, it features differential input and supports two channels. The device operates between -40°C and +105°C, drawing 2.5 mA during operation.
Feature Summary
- Class-AB topology eliminates EMI noise concerns without additional filtering requirements.
- HTSOP-J8 power package enables high output power density.
- Low quiescent current reduces battery consumption in standby mode.
- Minimal pop noise during shutdown transitions supports frequent state changes.
Applications
- Automotive audio systems
- Monaural speaker amplification
- Battery-powered vehicle electronics
Procurement Notes
Verify the specific suffix ME2 against the manufacturer's latest datasheet to confirm packaging and tape-and-reel specifications. Ensure the component meets AEC-Q100 Grade 2 requirements for your target automotive environment. Cross-reference the production line designation if replacing older variants like the EFJ series, as manufacturing lines differ despite identical electrical characteristics.
Selection Notes
Select this amplifier for designs requiring Class-AB performance without EMI mitigation complexity. The HTSOP-J8 package suits space-constrained automotive boards. Verify thermal management capabilities given the power dissipation in the specified load conditions. Confirm compatibility with differential input signals and required gain settings for the target audio application.
Part Context
This component belongs to the BD7832xEFJ-M series of automotive speaker amplifiers. It shares electrical characteristics with the BD78326EFJ-M but utilizes a different production line for efficiency. The series includes variants with gains ranging from 6 dB to 26 dB, all featuring low standby current and pop-noise reduction for automotive use.
Replacement Considerations
The BD78326EFJ-M is electrically equivalent but manufactured on a different production line. Both parts share identical datasheet specifications. No other direct substitutes are documented in the provided source material.
