  致力于提供高品质芯片的国内优秀模拟及数模混合芯片设计商上海类比半导体技术有限公司(下称“类比半导体”或“类比”)宣布推出小尺寸、低功耗、高性能、零漂移仪表放大器INA103和INA104。该系列产品仅需要一个外部电阻即可设置1到10000的增益,静态电流仅为1.3mA并具有优异的DC性能和AC性能。INA103/INA104高精度仪器放大器仅有0.8ppm的低非线性度以及最大20μV的输入失调电压,是高精度数据采集系统的理想选择,可应用于测量仪器及传感器接口。此外,INA103/INA104具有低噪声、低输入偏置电流、低功耗等特性,非常适合应用于医疗应用,例如ECG及血压仪等。

  产品特性

  • 便于使用

  · 外部电阻设置增益(1到10,000)

  · 宽供电电压范围(±2V到±19V)· 更高的性能,相较于3运放类仪器放大器· 低功耗,1.3mA 静态电流• 优异的DC 性能· 最大±20μV,输入失调电压

  · 最大2.0nA,输入偏置电流· 最低108dB 共模抑制比(G=10)• 低噪声· 17nV/√Hz@1kHz,输入噪声电压· 1.8μVPP (0.1Hz到10Hz)

  • 优异的AC 性能

  · 2MHz 带宽(G=1)

  • 工作温度: –40°C到125°C

  • 封装: MSOP-8,更节省电路板空间

  INA103/INA104采用优化的三运放结构,能够提供超高的共模抑制比,从而有效的支撑测试测量应用中所需要的高分辨率、高精密性能。此外,低至17nV/√Hz@1kHz,1.8 μVPP (0.1Hz到10Hz) 的低噪声电压及0.45 pA/√Hz的低噪声电流特性,使INA103/INA104非常适用于便携式仪器仪表以及其他电池供电的手持应用,高精度特性使其成为ECG运放等精密医疗应用的绝佳选择。在对于工作环境温度范围大、精度要求高的应用中,INA103和INA104所具有的低温漂特性使其可广泛应用在热电偶放大器等场景。
