• LTC6373 Output Amplifier Supply

    Hi,

    the LTC6373 has a nice option with the V+OUT pin for the supply of the output amplifier, where one can have a high supply voltage like +-15V for the input amplifiers in order to have a large input voltage range, and have a lower supply voltage for…

    如果输入信号阻抗比较大,同时你又需要高增益, 我觉得 低偏流的仪表放大器是更好的选择.因为运放输入端的偏流会乘以你的信号输入阻抗,产生一个失调的电压,从而影响你的输出误差,  你可以参考AD8220和LTC6373 这样的仪表放大器.,其输入偏流仅为10pA. 这样可以有效降低输入等效阻抗的影响.
