92HD95B2X3NDGXZAX8

Overview

The Tempo Semiconductor 92HD95 is a low-power, high-fidelity four-channel audio codec compatible with Intel High Definition Audio. It integrates two stereo DACs and two stereo ADCs with 24-bit resolution. The device includes a 3W Class-D BTL speaker amplifier, a true capless headphone amplifier with charge pump/LDO, and two digital microphone inputs. It operates on a 3.3V analog supply and supports selectable 1.5V or 3.3V HDA signaling. The component is housed in a 40-pin QFN package measuring 5mm x 5mm.

Feature Summary

Integrated Class-D BTL amplifier with hardware high-pass filter for speaker protection
Hardware compressor limiter to optimize volume without resonances
Supports combo jack detection for dual-function headset and headphone use
Capable of Runtime D3 low power mode with fast resume from inactivity

Applications

Notebook PC audio systems
Desktop PC audio platforms
Conference room voice capture applications
Lecture hall acoustic environments

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm pinout and feature configuration. Confirm RoHS compliance status and humidity sensitivity handling requirements during storage and assembly. Ensure the selected variant matches the required HDA signaling voltage level for the target system design.

Selection Notes

Select this component when a single-chip solution combining codec, speaker amplifier, and headphone driver is required. Consider the integrated hardware equalizer and limiter features for optimizing speaker performance in constrained acoustic spaces. Verify that the 40-pin QFN package dimensions fit the available PCB real estate constraints.

Part Context

This part belongs to the 92HD95 series of HD Audio codecs optimized for low power and cost-sensitive applications. It serves as a complete audio subsystem replacement for discrete amplifier and codec combinations in portable computing devices.
