    GENERAL DESCRIPTION
    The AD8397 comprises two voltage feedback operational amplifiers
    capable of driving heavy loads with excellent linearity. The
    common-emitter, rail-to-rail output stage surpasses the output
    voltage capability of typical emitter-follower output stages and
    can swing to within 0.5 V of either rail while driving a 25 Ω
    load. The low distortion, high output current, and wide output
    dynamic range make the AD8397 ideal for applications that
    require a large signal swing into a heavy load.
    Fabricated with Analog Devices, Inc., high speed extra fast
    complementary bipolar high voltage (XFCB-HV) process, the
    high bandwidth and fast slew rate of the AD8397 keep distortion to
    a minimum. The AD8397 is available in a standard 8-lead SOIC_N
    package and, for higher power dissipating applications, a thermally
    enhanced 8-lead SOIC_N_EP package. Both packages can operate
    from 40°C to +85°C.
