INA180A2IDBVR(LX) 电流感应放大器产品概述

INA180A2IDBVR(LX)是灵星芯微(LX)推出的一款单路高精度电流感应放大器,专为宽范围、低功耗电流检测场景设计。该器件通过放大分流电阻两端的差分电压实现电流测量,具备高共模抑制比、宽温度范围和超小型封装等特点,可广泛应用于工业电源、电池管理、汽车电子等领域。

一、核心功能与应用场景

电流感应放大器的核心作用是将分流电阻(Shunt Resistor)两端的微小电压信号放大,转化为便于ADC采集或控制系统识别的输出电压,间接计算出电路电流(公式:(I = V_{out}/(Gain \times R_{shunt})))。

INA180A2IDBVR(LX)的宽共模电压范围(-200mV~30V) 支持高边检测(分流电阻接电源正端与负载之间)和低边检测(分流电阻接负载与地之间),无需额外电平转换电路,简化设计。典型应用包括:

  • 电池管理系统(BMS):监测单体/电池组充放电电流,防止过充过放;
  • 工业电源:开关/线性电源输出电流闭环控制,提升效率与可靠性;
  • 电机驱动:直流/无刷电机电流监测,避免过载损坏;
  • 汽车电子:车载充电器、车灯/电机驱动电流检测(宽温适配车载环境);
  • 便携式设备:智能手机、充电宝充电电流监测,优化续航。

二、关键性能参数解析

INA180A2IDBVR(LX)平衡了精度、功耗与抗干扰能力,核心参数价值如下:

1. 高精度检测

  • 输入失调电压((V_{OS}))仅25μV、失调电流((I_{OS}))0.05μA,结合1μV/℃温漂,小电流(如10mΩ分流电阻下1mA电流对应的10μV信号)检测仍精准;
  • 共模抑制比(CMRR)100dB,有效抑制电源纹波、电磁干扰等共模噪声,提升信号纯净度。

2. 宽范围适配

  • 共模电压(-200mV~30V)覆盖12V/24V车载、48V工业电源等场景;
  • 差分电压(-30V~30V)承受短时间过压冲击,保护器件;
  • 工作温度(-40℃~125℃)满足工业/汽车级环境要求。

3. 低功耗与高速响应

  • 静态电流175μA,单电源(2.7V~5.5V)兼容3.3V/5V常见电源,适合电池供电设备;
  • 带宽210kHz、压摆率4V/μs,应对开关电源瞬态电流、电机动态负载等中等频率变化。

4. 低噪声设计

  • 噪声密度40nV/√Hz@1kHz,减少小信号检测的背景噪声,提升精度。

三、封装与供电特性

  • 封装:SOT-23-5超小型封装(2.9mm×1.6mm),节省PCB空间,适配高密度设计(如BMS多通道监测);
  • 供电:单电源供电无需双电源电路,最大电源宽度5.5V避免过压损坏;
  • 输出能力:8mA输出电流直接驱动ADC或小型负载,无需额外驱动。

四、产品优势与总结

INA180A2IDBVR(LX)核心优势:高精度+宽共模+低功耗+小封装+宽温适配,解决多领域电流检测痛点——BMS中适配多节电池串联的共模变化,电机驱动中实现实时闭环控制,便携设备中低功耗不影响续航。

综上,该器件是高性价比选择,适用于对精度、功耗和环境适应性有要求的工业、汽车、便携等场景。

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
