新品发布|类比半导体推出宽带低噪声轨到轨运算放大器OPA825/6/8

  类比半导体推出OPA825/6/8系列单通道、双通道及四通道轨到轨宽带低噪声运算放大器,主要用于优化精密信号采集、电流采样检测与传感器信号调理类电路设计。该系列集成轨对轨输入输出架构,典型静态电流仅720μA,兼具11MHz宽带宽与超低噪声特性,1kHz 噪声低至 8nV/√Hz,可高效平衡成本与综合性能。

  此外,OPA825/6/8拥有极低输入偏置电流,能够适配兆欧级高内阻信号源;内置RF/EMI抑制滤波器,支持300pF容性负载单位增益稳定:具备4kV HBM静电防护、过载无相位反转等稳健特性,大幅降低外围设计难度。电气规格上,器件支持宽压工作,常温区间最低1.8V供电,扩展温域可覆盖−40℃~+125℃,满足多工况低压应用需求。

  封装布局丰富齐全,单通道OPA825采用SOT23-5和SC70-5,双通道OPA826采用SOIC-8,MSOP-8和TSSOP-8,四通道OPA828采用SOIC-14和TSSOP-14,硬件适配性强。产品广泛适配多领域场景:

  ● HEV/EV 逆变器与电机控制

  ● 电池供电类仪器设备

  ● 车载充电机(OBC)及无线充电器

  ● 高级驾驶辅助系统 ADAS

  ● 电机相电流检测

  ● 各类传感器信号调理电路
