2.5MHz, Precision Operational Amplifier
Features
The Intersil HA-5135 is a precision operational amplifier
manufactured using a combination of key technological
advancements to provide outstanding input characteristics.
• Low Offset Voltage . . . . . . . . . . . . . . . . . . . . . 75µV (Max)
A Super Beta input stage is combined with laser trimming,
dielectric isolation and matching techniques to produce
75µV (Maximum) input offset voltage and 0.4µV/oC input
offset voltage average drift. Other features enhanced by this
process include 9nV/√Hz (Typ) Input Noise Voltage, 1nA
Input Bias Current and 140dB Open Loop Gain.
These features coupled with 120dB CMRR and PSRR make
the HA-5135 an ideal device for precision DC instrumentation
amplifiers. Excellent input characteristics in conjunction with
2.5MHz bandwidth and 0.8V/µs slew rate, make this
amplifier extremely useful for precision integrator and
biomedical amplifier designs. This amplifier is also well
suited for precision data acquisition and for accurate
threshold detector applications.
HA-5135 offers added features over the industry standard
OP-07 in regards to bandwidth and slew rate specifications.
For the military grade product, refer to the HA-5135/883 data

Application Information
Power Supply Decoupling
Saturation Recovery
Although not absolutely necessary, it is recommended that
all power supply lines be decoupled with 0.01µF ceramic
capacitors to ground. Decoupling capacitors should be
located as near to the amplifier terminals as possible.
Input and output saturation recovery time is negligible in
most applications. However, care should be exercised to
avoid exceeding the absolute maximum ratings of the
device.
Considerations For Prototyping:
Differential Input Voltages
The following list of recommendations are suggested for
prototyping.
Inputs are shunted with back-to-back diodes for overvoltage
protection. In applications where differential input voltages in
excess of 1V are applied between the inputs, the use of
limiting resistors at the inputs is recommended.
1. Resolving low level signals requires minimizing leakage
currents caused by external circuitry. Use of quality
insulating materials, thorough cleaning of insulating
surfaces and implementation of moisture barriers when
required is suggested.
2. Error voltages generated by thermocouples formed
between dissimilar metals in the presence of temperature
gradients should be minimized. Isolation of low level
circuity from heat generating components is
recommended.
Typical Applications
The excellent input and gain characteristics of HA-5135 are
well suited for precision integrator applications. Accurate
integration over seven decades of frequency using HA-5135,
virtually nullifies the need for more expensive chopper-type
amplifiers.
C
3. Shielded cable input leads, guard rings and shield drivers
are recommended for the most critical applications.
Large Capacitive Loads
When driving large capacitive loads (>500pF), a small value
resistor (≈50Ω) should be connected in series with the
output and inside the feedback loop.
Offset Voltage Adjustment (See Figure 3)
A 20kΩ balance potentiometer is recommended if offset
nulling is required. However, other potentiometer values
such as 10kΩ, 50kΩ and 100kΩ may be used. The
minimum adjustment range for given values is ±2mV. VOS
TC of the amplifier is optimized at minimal VOS. Tested
Offset Adjustment is |VOS + 1mV| minimum referred
to output.
