HA-2548
150MHz, High Slew Rate,
Precision Operational Amplifier
The HA-2548 is an op amp that offers a unique combination
of bandwidth, slew rate, and precision specifications. These
features can eliminate the need for composite op amp
designs and external calibration circuitry.
Optimized for gains
≥
5, the HA-2548 has a gain-bandwidth
product of 150MHz and a slew rate of 120V/
μ
s while
maintaining extremely high open loop gain (130dB Typ) and
low offset voltage (300
μ
V Typ). These specifications are
achieved through uniquely designed input circuitry and a
single ultra-high gain stage that minimizes the AC signal
path. Capable of delivering over 30mA of output current, the
HA-2548 is ideal for precision, high speed applications such
as signal conditioning, instrumentation, video/pulse
amplifiers and buffers.
For information on the military version of this device please
refer to the HA-2548/883 datasheet.
