BD88200GUL-E2

Overview

The BD88200GUL-E2 is a dual-channel, capacitorless (C-less) audio amplifier manufactured by ROHM Semiconductor. It operates within a power supply voltage range of 2.4 V to 5.5 V and delivers up to 80 mW per channel into a 16 Ω load or 60 mW per channel into a 32 Ω load. The device features a variable gain of 6 dB with external gain capability, an input current consumption of 2 mA, and a standby current of 0.1 µA. It achieves a signal-to-noise ratio of 101 dB and total harmonic distortion plus noise of 0.006% at 16 Ω. The unit utilizes a VCSP50L2 package measuring 2.1x2.1 mm with a thickness of 0.55 mm.

Feature Summary

• Capacitorless output architecture eliminates the need for large coupling capacitors, enabling compact board space utilization.
• Dual-channel configuration provides independent stereo audio amplification within a single integrated circuit.
• Low quiescent current design supports extended battery life in portable electronic devices.
• High signal-to-noise ratio ensures clear audio reproduction with minimal background noise interference.

Applications

• Portable media players requiring high-fidelity audio output
• Smartphones and mobile communication devices
• Digital voice recorders and dictaphones
• MP3 and MP4 player modules

Procurement Notes

Verify the specific suffix E2 against the manufacturer's official documentation to confirm compliance with environmental standards and material declarations. Ensure the ordering part number matches the exact package variant and revision level required for your design. Cross-reference the datasheet version date to confirm the technical specifications have not been updated. Confirm RoHS status directly from the component certificate rather than relying on general distributor listings.

Selection Notes

Select this component when a small form factor is critical due to its VCSP50L2 package dimensions. It is suitable for applications requiring low power consumption during operation and deep sleep modes. Consider the 6 dB fixed gain and external gain options if the input signal amplitude is limited. Verify that the target load impedance aligns with the specified 16 Ω or 32 Ω ratings to ensure optimal power delivery and thermal performance.

Part Context

This component belongs to the BD88 series of audio amplifiers from ROHM Semiconductor. The series focuses on delivering high-quality sound in miniature packages for consumer electronics. The BD88200GUL-E2 specifically targets portable devices where space constraints and battery efficiency are primary design drivers. It complements other ROHM audio solutions by offering a balance between performance metrics and physical size.

Replacement Considerations

Consult the official ROHM replacement guide for direct pin-compatible alternatives. Verify that any substitute maintains the same VCSP50L2 footprint and electrical characteristics. Check for updated revisions within the BD88 series that may offer improved thermal handling or different gain configurations.
