92HD87B1X5NDGXRAX

Overview

The Tempo Semiconductor 92HD87B1X5NDGXRAX is a low-power, high-fidelity single-chip audio codec designed for notebook and business desktop PC applications. It integrates four channels comprising two stereo DACs and two stereo ADCs with 24-bit resolution. The device supports full-duplex stereo audio and simultaneous VoIP operations at conversion rates up to 192 kHz. Key integrated components include a 2W/channel stereo speaker amplifier, a capless headphone amplifier, and an internal LDO for the digital core supply. It operates within a temperature range of 0°C to +70°C and utilizes a 40-pad QFN package.

Feature Summary

Integrates a 2W/channel stereo speaker amplifier and a capless headphone amplifier to minimize system BOM count.
Supports full HDA015-B low power requirements with rapid D3 to D0 transition capabilities.
Includes an internal LDO for digital core supply and provides a dedicated BTL high pass filter for speaker protection.
Features five analog ports with port presence detection and support for digital microphone inputs.

Applications

Notebook computer audio systems
Business desktop PC audio platforms
Full-duplex stereo audio and VoIP implementations

Procurement Notes

Verify the specific revision suffix (RA) against the datasheet to confirm the inclusion of the dedicated BTL high pass filter for speaker protection. Ensure that the ordering information matches the required pin configuration and software compatibility settings defined by IDT HD Sound utilities before finalizing procurement.

Selection Notes

Select this component when a compact PCB footprint and minimal system cost are primary design constraints. It is suitable for applications requiring integrated Class-AB amplification and capless headphone drivers without external discrete components. Verify that the platform supports the necessary Microsoft WLP premium logo compliance standards.

Part Context

This part belongs to the 92HD87 series of single-chip PC audio systems manufactured by Tempo Semiconductor. The series is characterized by high integration levels that combine codec functionality with power amplification and voltage regulation in a small form factor.
