FN2907.5

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

75µV (Maximum) input offset voltage and 0.4µV/

o

C 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

sheet.

HA-5135

Application Information

Power Supply Decoupling

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.

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 (≈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.
