INA180A1IDBVR(LX) 单路电流感应放大器产品概述

INA180A1IDBVR是灵星芯微(LX)推出的一款单路电流感应放大器,针对中速、高精度电流监测场景优化,具备宽共模电压范围、低功耗、宽温工作等核心特性,适配工业、汽车电子、消费电子等多领域应用需求。

一、产品核心功能与定位

作为集成化电流感应器件,INA180A1IDBVR的核心功能是将采样电阻上的微小差分电流信号(mV级)放大为便于后级电路(如ADC、MCU)处理的电压信号(V级)。其单路设计聚焦单点电流监测,无需外部电阻调节增益,可替代传统“运放+电阻”的离散方案,简化系统设计并提升可靠性,适合对通道数量要求不高但精度、功耗有明确需求的场景。

二、关键性能参数解析

1. 信号放大与带宽特性

  • 固定增益:20V/V,无需外部电阻校准,降低设计复杂度;
  • 带宽:350kHz,覆盖中速电流信号(如开关电源输出电流、电机动态电流)的频率范围;
  • 压摆率:2V/μs,确保快速变化的瞬态电流(如负载突变)被准确放大,无明显失真。

2. 精度与抗干扰能力

  • 输入失调电压(Vos):100μV,低失调减少静态误差,提升小电流(mA级以下)检测精度;
  • 失调电压温漂(Vos TC):1μV/℃,宽温范围内保持精度稳定,适应环境温度波动;
  • 共模抑制比(CMRR):100dB,对共模干扰(如电源纹波、电磁噪声)抑制能力强,适合高压共模场景(如汽车12V/24V系统、工业24V电源);
  • 噪声密度:40nV/√Hz@1kHz,低噪声可检测微弱电流信号,避免噪声淹没有用信号。

3. 功耗与电流特性

  • 静态电流(Iq):175μA,低功耗设计适配电池供电设备(如便携式仪器、智能穿戴)或功耗敏感系统;
  • 输入偏置电流(Ib):75μA,输入电流小,对采样电阻的负载影响可忽略;
  • 输入失调电流(Ios):50nA,进一步降低输入电流差异带来的误差。

4. 电压与输出范围

  • 单电源工作:2.7V~5.5V,适配常见MCU/ADC供电电压,无需双电源;
  • 共模电压范围:-200mV~30V,支持高压侧电流检测(如直接监测24V电源线上的电流),无需电平转换;
  • 差分电压范围:-30V~+30V,兼容宽范围差分信号输入;
  • 输出电流:8mA,可驱动小负载(如ADC输入、LED指示电路)。

三、封装与工作环境

  • 封装:SOT-23-5,体积小巧(约2.9mm×1.6mm),适合高密度PCB设计,满足小型化产品需求;
  • 工作温度:-40℃+125℃,宽温范围覆盖工业级(-4085℃)和部分汽车级场景,适应户外设备、车载电子等恶劣环境。

四、典型应用场景

  1. 工业设备电流监测:电机、变频器、PLC的电流检测,宽共模电压适配24V/48V工业电源,350kHz带宽满足动态电流监测;
  2. 汽车电子:电池管理系统(BMS)充放电电流监测、车载充电器电流反馈,单电源适配12V车载电源,宽温满足车载环境;
  3. 消费电子:便携式仪器、智能音箱的电池电流监测,175μA低功耗延长续航;
  4. 电源管理:开关电源、LED驱动电源的输出电流反馈,20V/V固定增益简化设计,高CMRR抑制电源纹波干扰。

五、选型核心优势

  • 宽共模适配:-200mV~30V无需额外电路,直接检测高压侧电流,简化系统架构;
  • 低功耗集成:175μA静态电流+固定增益,替代离散方案,降低功耗与BOM成本;
  • 高抗干扰精度:100dB CMRR+40nV/√Hz噪声,提升复杂环境下的电流检测精度;
  • 宽温小封装:-40~125℃适应恶劣环境,SOT-23-5节省PCB空间,适合小型化产品。

INA180A1IDBVR通过集成化设计平衡了精度、功耗与成本,是中速电流监测场景的高性价比选择。

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
