【产品】36V 8MHz精密低噪声运算放大器COS27,输入失调电压最大50μV
科山芯创的COS27是一款低功耗、精密运算放大器,工作电压范围±2.25V ~ ±18V。通过晶圆修正,它的输入失调电压极低(最大50μV ),低失调电压无需外部调零。拥有极低的输入偏置电流及高开环增益、低失调及高增益,使得COS27非常适合应用在高增益设备上。
COS27的宽输入电压范围(最低±13V,±15V供电)、高共模抑制比(110dB)及高输入阻抗特性,使得该产品在同相放大电路中有极高的精度。在高闭环增益情况下,其线性增益和增益精度非常好;在时间及温度变化的情况下,失调及增益仍非常稳定。上述特性使得COS27非常适合仪器、仪表应用。

【经验】国产高精度运放SGM8254/SGM8554对热电偶信号的多级放大处理
热电偶以电动势的形式输出,输出毫伏级电压,因热电偶本身是无源器件,本身无驱动能力,后级放大电路要求很高的输入阻抗,国产高精度运放供应商SGMICRO为热电偶的信号处理提供了SGM8554和SGM8254多级放大方案.

【经验】解析运算放大器的Vos对实际电路的影响和调整方法
0PA的Vos(输入失调电压)主要是因OPA输入级的管子不能完全对称造成的,Vos通常是等效在0PA的同相输入端一个电压源,在实际应用中因0PA的Vos大小会带来不同的影响,思瑞浦将在本文列举几个例子来说明Vos对实际电路的影响和调整方法.
