BH7823AFVM-TR

Overview

The BH7823AFVM-TR is a monaural Class-AB audio power amplifier manufactured by Rohm Semiconductor, designed for mobile audio appliances. It operates within a supply voltage range of 2.8V to 5.5V and delivers up to 500mW into an 8Ω load using BTL configuration. The device features low power consumption with suspend control reducing current to 0µA (typical). Key electrical parameters include a typical circuit current of 1.6mA in active mode and 0µA in suspend mode. It incorporates built-in anti-pop and thermal shutdown circuits.

Feature Summary

• BTL monaural audio power amplifier architecture
• Suspend control for zero standby current
• Built-in anti-pop and thermal protection

Applications

• Cellular phones
• Palm PCs
• Hand-held appliances

Procurement Notes

Verify the specific suffix 'FVM' corresponds to the MSOP-8 package and TR indicates tape-and-reel packaging. Confirm RoHS compliance status as per the latest datasheet revision. Check for End-of-Life or Not Recommended for New Designation status before finalizing procurement plans.

Selection Notes

Select this component for applications requiring high output power from a single channel in a compact form factor. Ensure the design supports BTL topology to achieve the specified 500mW output. Verify that the system voltage remains within the 2.8V to 5.5V operating range for optimal performance.

Part Context

This part belongs to Rohm's BH7823 series of audio drivers specifically engineered for low-voltage mobile devices. It utilizes an MSOP-8 surface-mount package to minimize board space. The device integrates two operational amplifiers to drive the speaker load directly without external coupling capacitors.
