About this product

Overview

  • 4 dual input, internally compensated amplifiers designed primarily for single power rail operation
  • Current differencing amplifiers use a current mirror to achieve the non-inverting function

Product overview

• 4 dual input, internally compensated amplifiers designed primarily for single power rail operation• Current differencing amplifiers use a current mirror to achieve the non-inverting function

When driving from a low impedance source a resistor should be placed in series to limit the peak input current to less than 20mA.
