Overview
The BD8878FV-E2 is a two-channel line amplifier manufactured by ROHM Semiconductor, housed in an SSOP-B14 package. It operates on a single power supply ranging from 3V to 5.5V with a typical circuit current of unspecified low values and a standby current of 0.1µA. The device features a fixed gain of 6.7dB and delivers a maximum output of 3Vrms into a 10kΩ load. Key electrical parameters include a signal-to-noise ratio of 109dB, total harmonic distortion plus noise of 0.003%, and a power supply rejection ratio of -65dB. It supports ground-referenced outputs without coupling capacitors and functions within an operating temperature range of -40°C to 85°C.
Feature Summary
- Integrated negative voltage generator enables capacitor-less operation with ground-referenced outputs
- Fixed gain configuration provides consistent amplification for line-level signals
- Built-in short-circuit and thermal protection mechanisms ensure operational reliability
Applications
- Audio subsystems requiring ground-referenced line amplification
- Portable electronic devices utilizing single-supply architectures
- Consumer audio equipment needing low-power signal processing
Procurement Notes
Verify the specific suffix E2 against official ROHM documentation to confirm RoHS compliance and packaging details. Ensure the design utilizes a single supply voltage between 3V and 5.5V. Confirm that the application does not require variable gain, as this model has a fixed gain configuration. Check for availability status as product lifecycles may change.
Selection Notes
Select the BD8878FV-E2 when a fixed gain of 6.7dB is required for two-channel audio applications. This component is suitable for designs where space savings from eliminating coupling capacitors are prioritized. Consider the BU8786FV variant if variable gain options (+6dB or +9dB) are necessary instead of the fixed gain provided here.
Part Context
This component belongs to ROHM's line amplifier portfolio, which includes speaker amplifiers, headphone amplifiers, and audio subsystems. The BD8878FV-E2 is part of a series designed for efficient audio signal processing in compact consumer electronics. It shares architectural similarities with other capacitor-less amplifiers in the lineup but differs in gain configuration and channel count compared to broader audio IC families.
Replacement Considerations
The BD8876FV is a documented alternative within the same family. It offers variable gain options (+6dB / +9dB Typ.) whereas the BD8878FV-E2 provides a fixed gain (+6.7dB Typ.). Both share identical channel counts, packages, and core functionalities.
