HA-5127, HA-5127A
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
(10
μV), 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.

NOTES:
1. These Intersil Pb-free plastic packaged products employ special Pb-
free material sets, molding compounds/die attach materials, and
100% matte tin plate plus anneal (e3 termination finish, which is
RoHS compliant and compatible with both SnPb and Pb-free
soldering operations). Intersil Pb-free products are MSL classified
at Pb-free peak reflow temperatures that meet or exceed the Pb-
free requirements of IPC/JEDEC J STD-020.
