  • These circuits are high speed J–FET input quad operational amplifiers incorporating well matched, high voltage J–FET and bipolar transistors in a monolithic integrated circuit.

    The devices feature high slew rates, low input bias and offset currents, and low offset voltage temperature coefficient.

    Key Features

    • Low power consumption
    • Wide common-mode (up to VCC+) and differential voltage range
    • Low input bias and offset current
    • Output short-circuit protection
    • High input impedance J-FET input stage
    • Internal frequency compensation
    • Latch up free operation
    • High slew rate: 16v/ms (typ)
