NAU88L21YG 产品概述

一、产品简介

NAU88L21YG 是 NUVOTON(新唐)面向便携与低功耗音频终端设计的一款 G 类双声道功放芯片。芯片集成 PLL 与音频处理模块,支持多路输入配置,适用于对功耗、体积和音质均有要求的移动设备与智能终端。

二、主要性能指标

  • 功放类型:G 类功放,兼顾效率与模拟音质。
  • 输出功率:33 mW × 2(16Ω),28 mW × 2(32Ω),适合小口径扬声器或耳机驱动。
  • 总谐波失真+噪声(THD+N):1%,在常见听音场景下保持良好线性表现。
  • 信噪比(SNR):105 dB,保证背景底噪低,细节保真。
  • 电源纹波抑制比(PSRR):90 dB,有利于消除电源噪声对音频的干扰。
  • 工作电压:1.62 V ~ 1.98 V,兼容低电压供电系统;工作温度范围:-40℃ ~ +85℃。

三、输入与接口

  • 模拟输入:2 个单端输入 + 2 对差分输入,灵活支持多种麦克风/线路接入方式。
  • 描述:接口功能完备(详见数据手册),芯片内置音频处理模块,通常通过片上控制接口进行参数配置与寄存器访问。

四、封装与系统集成

  • 封装:QFN-32-EP(5×5 mm),适合高密度 PCB 设计与自动贴装。
  • 封装散热需结合 EP(exposed pad)接地焊盘良好布局,保证热量与信号完整性。
  • 在系统设计中建议采用严格的电源去耦、差分线路布线与地平面分离,以发挥高 PSRR 与 SNR 特性。

五、典型应用场景与注意事项

  • 适用场景:TWS 耳机、便携媒体播放器、智能音箱边缘模块、可穿戴设备等对功耗与音质有平衡要求的产品。
  • 设计注意:低电压供电下需评估输出驱动能力与失真表现;差分输入优先用于抑制共模噪声;调试时参考厂商评估板与寄存器配置示例,以获得最佳音质与稳定性。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
