92HD91B2X5NLGIWCX

Overview

The Tempo Semiconductor 92HD91B2X5NLGIWCX is a single-chip PC audio system featuring a low-power, high-fidelity 4-channel audio codec with an integrated Class-D speaker amplifier, capless headphone amplifier, and internal LDO. It provides two stereo DACs and two stereo ADCs with 24-bit resolution. The device supports full-duplex stereo audio, simultaneous VoIP, and 2.1 audio crossover. It operates within a supply voltage range of 3.135 V to 5.25 V and functions across a temperature range of -40°C to +85°C. The component utilizes a 48-pad QFN package for surface mount installation.

Feature Summary

Integrated 3W/channel Class-D stereo BTL speaker amplifier supporting 4-ohm loads at 5V
Capless headphone amplifier utilizing charge pump and LDO technology
Full HDA 015-B low power support enabling rapid D3 to D0 transitions under 10 msec
Hardware parametric equalizer and compressor limiter for dynamic processing

Applications

Notebook computer audio systems
Business desktop PC audio platforms
