2.5MHz, Precision Operational Amplifier
The Intersil HA-5135 is a precision operational amplifier manufactured using a combination of key technological advancements to provide outstanding input characteristics. A Super Beta input stage is combined with laser trimming, dielectric isolation and matching techniques to produce 75V (Maximum) input offset voltage and 0.4V/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/s 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 sheet.

HA-5135 Application Information
Power Supply Decoupling
Although not absolutely necessary, it is recommended that all power supply lines be decoupled with 0.01F ceramic capacitors to ground. Decoupling capacitors should be located as near to the amplifier terminals as possible.
Saturation Recovery
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:
The following list of recommendations are suggested for prototyping. 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. 3. Shielded cable input leads, guard rings and shield drivers are recommended for the most critical applications.
Differential Input Voltages
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.
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
Large Capacitive Loads
When driving large capacitive loads (>500pF), a small value resistor (50) should be connected in series with the output and inside the feedback loop.

Offset Voltage Adjustment (See Figure 3)
A 20k balance potentiometer is recommended if offset nulling is required. However, other potentiometer values such as 10k, 50k and 100k 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.
