J-FET Input Low-power QUAD OperationAL AMPLIFIER

The μPC4064 is a low power J-FET input quad operational amplifier that will operate at voltage levels as low as ±2 V. Input current is typically less than 1mA. With input bias and offset currents as low as a few pA, the μPC4064 is an excellent choice for hand-held measurement equipment. ? Low supply current: 800 μA (TYP.)\n?
