Data Sheet
HA-5127, HA-5127A
September 1998 File Number 2906.4
8.5MHz, Ultra-Low Noise
Precision Operational Amplifier
The HA-5127 monolithic 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 (3nV/√Hz) precision
instrumentation performance with high speed (10V/µs)
wideband capability.
This amplifier’s impressive list of features include low VOS
(10µV), wide unity gain-bandwidth (8.5MHz), high open loop
gain (1800V/mV), and high CMRR (126dB). Additionally, this
flexible device operates over a wide supply range (±5V to
±15V) while consuming only 140mW of power.
Using the HA-5127 allows designers to minimize errors while
maximizing speed and bandwidth.
This device is ideally suited for low level transducer signal
amplifier circuits. Other applications which can utilize the
HA-5127’s qualities include instrumentation amplifiers, pulse
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. For the military grade product, refer
to the HA-5127/883 data sheet.

Low resistances are preferred for low noise applications as a 1kΩ resistor has 4nV/√Hz of thermal noise. Total resistances of greater than 10kΩ on either
input can reduce stability. In most high resistance applications, a few picofarads of capacitance across the feedback resistor will improve stability.
