DESCRIPTION

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.

FEATURES

• Low supply current: 800

µA (TYP.)

• Very low input bias and offset currents

• High input impedance...J-FET Input Stage

• Low supply voltage operation

• Output short circuit protection

• Internal frequency compensation
