BD8876FV-E2

Overview

The BD8876FV-E2 is a two-channel line amplifier manufactured by ROHM Semiconductor, designed for audio signal processing applications. It operates within a power supply voltage range of 3 V to 5.5 V and supports an operating temperature range from -40°C to 85°C. The device features a variable gain configuration with typical settings of +6 dB or +9 dB. Key electrical parameters include a maximum output of 3.5 Vrms into a 10 kΩ load, a total harmonic distortion plus noise (THD+N) of 0.003%, and a signal-to-noise ratio (S/N) of 112 dB. The unit draws a standby current of 0.1 µA and has a startup time of 470 µs. It is housed in an SSOP-B14 package.

Feature Summary

• Integrates a negative power supply generator to enable ground-referenced outputs without external coupling capacitors
• Supports variable gain selection with typical values of +6 dB or +9 dB
• Includes integrated short-circuit and thermal protection mechanisms

Applications

• Audio signal processing circuits requiring capacitor-less output stages
• Portable electronic devices utilizing single-supply operation
• General-purpose line amplification in consumer electronics

Procurement Notes

Verify the specific ordering suffix, such as -E2, to ensure compliance with RoHS directives and packaging requirements. Confirm that the application environment remains within the specified -40°C to 85°C operating temperature range. Ensure the design does not target automotive equipment, as this product is classified as standard grade and is not recommended for such use cases.

Selection Notes

Select this component when designing audio systems that require high dynamic range output from a single low-voltage supply. The built-in negative voltage generator eliminates the need for external charge pumps or dual supplies. Consider the variable gain options if flexible amplification levels are required. Verify that the SSOP-B14 package dimensions fit the available PCB space constraints.

Part Context

This part belongs to ROHM's lineup of line amplifiers, which also includes speaker amplifiers and headphone amplifiers. The BD8876FV-E2 is distinct from the BD8878FV model, which offers a fixed gain of +6.7 dB instead of the variable gain found in the BD8876FV. Both models share similar package and operational characteristics but differ in gain configuration flexibility.

Replacement Considerations

The BD8878FV is a similar specification alternative within the same family. It provides a fixed gain of +6.7 dB compared to the variable gain of the BD8876FV. Both parts utilize the SSOP-B14 package and share identical power supply and temperature specifications.
