HA-2505
12MHz, High Input Impedance,
Operational Amplifier
HA-2505 is an operational amplifier whose design is
optimized to deliver excellent slew rate, bandwidth, and
settling time specifications. The outstanding dynamic
features of this internally compensated device are
complemented with low offset voltage and offset current.
This dielectrically isolated amplifier is ideally suited for
applications such as data acquisition, RF, video, and pulse
conditioning circuits. Slew rates of
30V/
s and 330ns
(0.1%) settling time make this device an excellent
component in fast, accurate data acquisition and pulse
amplification designs. 12MHz small signal bandwidth and
500kHz power bandwidth make this device well suited to RF
and video applications. With 2mV typical offset voltage plus
offset trim capability and 10nA offset current, HA-2505 is
particularly useful in signal conditioning designs.
The gain and offset voltage figures of the HA-2505 are
optimized by internal component value changes while the
similar design of the HA-2515 is maximized for slew rate.
MIL-STD-883 product and data sheets are available upon
request.
