ISL60002DAH333Z-TK 产品概述

一、产品简介

ISL60002DAH333Z-TK 为瑞萨(RENESAS)系列精密串联电压基准芯片,固定输出 3.3V,面向对精度、低噪声和超低静态电流有严格要求的便携及工业应用。器件采用 SOT-23-3 小外形封装,输入工作电压范围 3.5V ~ 5.5V,输出电流可驱动至 20mA,静态电流仅 700nA,典型噪声 0.1Hz–10Hz 为 30 µVpp,器件初始精度±0.15%,温度系数 20 ppm/°C,工作温度范围 -40°C ~ +105°C。该器件属于串联(series)基准结构,适合作为 ADC/DAC 基准、精密电源节点及监测电路的参考电压源。

二、主要性能参数

  • 输出类型:固定(3.3V)
  • 输入工作电压:3.5V ~ 5.5V
  • 最大输出电流:20 mA(短时大电流驱动,连续时请参考热设计)
  • 初始精度:±0.15%
  • 温度系数(TC):20 ppm/°C
  • 电压基准类型:串联(series bandgap)
  • 静态电流(Iq):700 nA(typ)
  • 输出噪声(0.1Hz–10Hz):30 µVpp
  • 工作温度范围:-40°C ~ +105°C
  • 封装:SOT-23-3(小尺寸,适合空间受限系统)

三、芯片特性与优势

  • 极低静态电流:700 nA 的工作电流非常适合电池供电或超低功耗设计,能显著降低待机功耗。
  • 高精度与低温漂:±0.15% 的初始误差配合 20 ppm/°C 的温度系数,保证在全温区内的电压稳定性,适合高精度测量场景。
  • 低频低噪声:0.1Hz–10Hz 仅 30 µVpp,保证在微弱信号测量(如桥式传感器、低频 ADC)中不会显著退化系统性能。
  • 紧凑封装:SOT-23-3 封装便于小型模块化设计与量产组装。

四、典型应用

  • 精密 ADC/DAC 基准电压
  • 便携式/电池供电设备的低功耗参考源
  • 温度传感器、压力传感器等传感前端参考
  • 电源管理芯片的参考节点与基准源
  • 数据采集系统、便携测量仪器、物联网节点

五、应用建议与参考电路

  • 电路连接:VIN 接至输入电源(3.5V~5.5V),GND 接地,VOUT 提供 3.3V 输出给负载与系统参考。
  • 去耦与稳定:建议在 VOUT 侧靠近器件引脚放置 0.1 µF ~ 1 µF 低 ESR 陶瓷电容以降低输出噪声并改善瞬态响应;输入侧建议放置 0.1 µF 去耦电容以滤除电源干扰。具体数值以系统测试结果为准。
  • 布局要点:VOUT 电容与器件引脚应尽量靠近(≤1 mm),走短而宽的电源与地线,使用连续地平面以降低温差与串扰。对敏感 ADC 输入,避免把参考线与高频开关或大电流回路并行。
  • 功耗与热设计示例:最大输出功耗主要由 VIN-VOUT 乘以负载电流决定。例如 VIN = 5.5V、VOUT = 3.3V、Iout = 20 mA 时,P ≈ (5.5–3.3)V × 20 mA = 44 mW(Iq 功耗可忽略)。SOT-23-3 封装对该功耗通常可接受,但在高环境温度或密集布板下应留出热余量并采用大面积铜箔散热。
  • 保护与容错:若负载或系统可能引起短路或反向电压,应在输入端加入合适的串联保护、保险丝或限流元件,并在必要时增加反向保护二极管。

六、封装与环境适配

  • 封装:SOT-23-3,适合自动贴片生产与标准焊盘工艺。封装尺寸小、占板面积低,但散热能力受限,关注热阻与环境温度。
  • 工作温度:-40°C 至 +105°C,适用于工业级应用。
  • 储存与处理:按行业惯例遵守防潮封装与回流焊温度限制,贴片后建议进行适当的回流曲线控制,避免高温长时间暴露。

七、选型与采购建议

  • 型号说明:ISL60002DAH333Z-TK 为 3.3V 固定输出版本,TK 通常表示包装形式(例如卷带),具体含义请以瑞萨官方物料编码为准。
  • 设计确认:在最终设计前,务必参照瑞萨最新数据手册确认电气参数、典型特性曲线和封装机械图。针对噪声、瞬态响应和输出驱动能力,建议在目标系统中做实际测量验证。
  • 替代与扩展:若需其他输出电压或更高驱动能力,可查询同系列或相近产品,注意比较温漂、噪声与工作电流等关键指标。

总结:ISL60002DAH333Z-TK 提供兼顾高精度、低温漂和超低静态电流的 3.3V 基准解决方案,适合对功耗与测量性能都有严格要求的便携与工业应用。在布局、去耦和热管理上适当优化,可充分发挥其性能优势。

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.
