This amplifier’s impressive list of features include low V
OS
(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 (±5V to
±20V) while consuming only 140mW of power.
Applications
• High Speed Signal Conditioners
• Wide Bandwidth Instrumentation Amplifiers
• Low Level Transducer Amplifiers
• Fast, Low Level Voltage Comparators
• Highest Quality Audio Preamplifiers
• Pulse/RF Amplifiers
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.

Pinout
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. For military grade
product, refer to the HA-5147/883 data sheet.
