Overview
The 92HD91B2X5NLGIWCX8 is a high-definition audio codec manufactured by Renesas Electronics Corporation. It features a 4-channel architecture with 2 ADCs and 2 DACs, supporting 24-bit resolution and sample rates up to 192 kHz. The device operates within an analog supply voltage range of 4.75 V to 5.25 V and a digital supply voltage range of 3.135 V to 3.465 V. It incorporates Class D amplifier outputs and supports HDA and S/PDIF interfaces. The component is housed in a 48-VFQFN package with exposed pad and functions reliably across an operating temperature range of 0°C to 70°C.
Feature Summary
- Integrates Class D amplifier outputs for direct speaker driving capability
- Supports High Definition Audio (HDA) and S/PDIF digital interfaces
- Provides stereo 24-bit resolution with high sample rate support
Applications
- Notebook computer audio systems
- Media-centric desktop PC applications
- High-definition audio interface modules
Procurement Notes
Verify the manufacturer designation carefully, as this part number appears in distributor listings under Tempo Semiconductor while the brand specified is Renesas Electronics Corporation. Confirm the exact suffix and RoHS compliance status against the official datasheet before integration. Ensure the sourcing channel provides authentic components matching the 48-VFQFN package specifications.
Selection Notes
Select this component for designs requiring integrated Class D amplification alongside standard audio conversion. It is suitable for space-constrained applications utilizing the 48-VFQFN footprint. Verify that the system power rails align with the specified 5V analog and 3.3V digital supply requirements. Consider the thermal performance of the QFN package for the target enclosure environment.
Part Context
This device belongs to the 92HD91 series of high-definition audio codecs. The series is designed for notebook and desktop PC platforms, offering a balance of audio fidelity and power efficiency. The specific model integrates amplifier stages, distinguishing it from basic codec variants that require external power amplifiers.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing with the broader 92HD91 family may reveal pin-compatible alternatives, but specific functional equivalence must be verified through official Renesas or Tempo Semiconductor technical documents.
