Overview
The BD88210GUL-E2 is a stereo Class AB audio amplifier designed for coupling capacitor-less headphone applications. It operates on a single power supply ranging from 2.4V to 5.5V and features an integrated negative voltage generator using a regulated charge pump. The device delivers up to 60mW per channel into a 32Ω load or 80mW into 16Ω. Key electrical specifications include a signal-to-noise ratio of 101dB, total harmonic distortion plus noise of 0.006% at 16Ω, and a standby current of 0.1µA. It functions within a temperature range of -40°C to 85°C.
Feature Summary
- Integrates a regulated charge pump circuit to generate negative voltage from a single positive supply, enabling direct drive without output coupling capacitors.
Applications
- Capacitor-less headphone amplification in portable devices
- Single-supply audio systems requiring low quiescent current
Procurement Notes
Verify the specific suffix (E2) against the manufacturer's latest documentation to confirm compliance with current environmental standards and pinout configurations. Ensure the VCSP50L2 package dimensions align with the target PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when designing compact audio circuits that require elimination of bulky output capacitors. It is suitable for battery-powered applications due to its low standby current and wide operating voltage range. Verify thermal performance under maximum load conditions given the small package size.
Part Context
This part belongs to the BD88210 series of ROHM Semiconductor audio amplifiers. It shares architectural similarities with related models like the BD88410GUL but is specifically optimized for stereo headphone driving capabilities. The series focuses on high-fidelity audio reproduction in minimal form factors.
Replacement Considerations
The BD88220GUL-E2 is a documented substitute within the same family. Verify functional equivalence regarding output power and pin compatibility before substitution.
