HA-5147 Features The HA-5147 operational amplifier features an unparalleled
combination of precision DC and wideband high speed
characteristics. Utilizing the Intersil D. I. technology and
advanced processing techniques, this unique design unites low
noise (3.2nV/пѓ–Hz) precision instrumentation performance with
high speed (35V/µs) wideband capability. Slew rate . 35V/µs This amplifier’s impressive list of features include low VOS
(30mV), wide gain bandwidth (120MHz), high open loop gain
(1500V/mV) and high CMRR (120dB). Additionally, this flexible
device operates over a wide supply range (В±5V to В±20V) while
consuming only 140mW of power.
Using the HA-5147 allows designers to minimize errors while
maximizing speed and bandwidth in applications requiring
gains greater than ten.
This device is ideally suited for low level transducer signal
amplifier circuits. Other applications which can utilize the
HA-5147’s qualities include instrumentation amplifiers, pulse
or RF amplifiers, audio preamplifiers and signal conditioning
circuits.
This device can easily be used as a design enhancement by
directly replacing the 725, OP25, OP06, OP07, OP27 and
OP37 where gains are greater than ten.
