HA-5137A
63MHz, Ultra-Low Noise Precision
Operational Amplifier
The HA-5137 operational amplifier features an unparalleled
combination of precision DC and wideband high speed
characteristics. Utilizing the Intersil Dielectric Isolation
technology and advanced processing techniques, this
unique design unites low noise
precision
instrumentation performance with high speed (20V/
s)
wideband capability.
This amplifier's impressive list of features include low V
OS
(10
V), wide gain bandwidth (63MHz), high open loop gain
(1800V/mV), and high CMRR (126dB). Additionally, this
flexible device operates over a wide supply range (
5V to
20V) while consuming only 140mW of power.
Using the HA-5137 allows designers to minimize errors while
maximizing speed and bandwidth in applications requiring
gains greater than five.
This device is ideally suited for low level transducer signal
amplifier circuits. Other applications which can utilize the
HA-5137'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 five. For the military
grade product, refer to the HA-5137/883 data sheet.

Application Information
NOTE:
Tested Offset Adjustment Range is |V
OS
+ 1mV| minimum referred to output. Typical range is
4mV with R
P
= 10k
.
FIGURE 3. SUGGESTED OFFSET VOLTAGE ADJUSTMENT
NOTE: Low resistances are preferred for low noise applications as a 1k
resistor has 4nV/
Hz of thermal noise. Total resistances of greater than
10k
on either input can reduce stability. In most high resistance applications, a few picofarads of capacitance across the feedback resistor will
improve stability.
