AZV831KTR-G1 产品概述

一、概述

AZV831KTR-G1 是 DIODES(美台)推出的一款单路运算放大器,封装为 SOT-23-5。器件强调低功耗与高输入阻抗,支持轨到轨输入与轨到轨输出,适合便携和电池供电系统中的精密信号处理。工作温度范围为 -40℃ 至 +85℃。

二、主要电气参数

  • 放大器数:单路
  • 最大电源宽度 (Vdd–Vss):5.5V
  • 单电源工作范围:1.6V ~ 5.5V;双电源:Vee ~ Vcc = -0.8V ~ 2.5V
  • 增益带宽积(GBP):1MHz
  • 压摆率(SR):0.45 V/µs(450 V/ms)
  • 输入失调电压(Vos):典型 500 µV,温漂 2 µV/℃
  • 输入偏置电流(Ib):1 pA;输入失调电流(Ios):1 pA
  • 噪声密度:27 nV/√Hz @1 kHz
  • 共模抑制比(CMRR):75 dB
  • 静态电流(Iq):70 µA
  • 输出电流能力:185 mA(短时/驱动能力需参照具体应用)

三、性能特点与优势

  • 轨到轨输入/输出可充分利用低电压单电源,最低仅 1.6V 即可工作,适合便携设备与低功耗系统。
  • 极低的输入偏置电流(1 pA)和低失调漂移使其非常适合高阻传感器、精密电荷放大/测量场合。
  • 1 MHz 的 GBP 适合多种低频滤波器、缓冲和放大任务;27 nV/√Hz 的噪声水平适合要求中等噪声的前端放大。
  • 70 µA 的静态电流在保持低功耗的同时提供较强的输出驱动能力(185 mA),对单片机外围驱动或短时负载冲击有利。

四、典型应用场景

  • 电池供电的传感器接口(温湿度、光电、气体传感等)
  • 精密缓冲放大器、滤波器(低通、带通)与仪表放大前端
  • 采集系统的ADC驱动与信号调理
  • 低功耗便携设备、可穿戴电子以及数据采集模块

五、使用建议与注意事项

  • 电源去耦:靠近封装布置 0.1 µF 至 1 µF 陶瓷去耦电容以保证稳定性与抗干扰。
  • 大电容性负载:输出直接驱动大电容可能引发振荡,建议串联小阻抗(10–100 Ω)或缓冲器。
  • 布局要点:高阻输入节点需避开噪声源,提供干净的地回流路径以保留低偏置和低噪声优势。
  • 带宽与速率限制:GBP 1 MHz 与 SR 0.45 V/µs 在处理高速大幅度波形时会限制瞬态响应,应在系统设计中评估闭环增益与所需带宽。

六、封装与订购信息

  • 封装:SOT-23-5,适合空间受限的表贴应用。
  • 品牌:DIODES(美台)
  • 订购时请参考完整型号 AZV831KTR-G1 并确认器件批次与可靠性规格(如需工业或特殊温度等级,请与供应商确认)。

总结:AZV831KTR-G1 将低功耗、高输入阻抗与轨到轨性能结合,适合对直流精度和低偏置要求高且供电受限的便携和工业应用。在系统设计阶段注意带宽、压摆率和负载特性,可充分发挥其在传感器接口与信号调理方面的优势。

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
