544UD1B

Operational difference amplifier with high input resistance, low level of input current, built-in frequency compensation, allowing the usage with all modes of negative feedback, including integrator and voltage repeater modes. The complex of characteristics allows this IC to be used instead of other operational amplifiers, as well as an integrator with long integration time and high accuracy, in electrometers and logarithmic amplifiers with extended logarithmation range. Low noise current and good noise voltage spectrum characteristics allows to use the amplifier for high-resistance photoelectric receivers with current-to-voltage conversion, sample-and-hold circuits and high-resistance buffers.
