INA128U Typical application Circuitry

INA128U

The INA128U is a precision instrumentation amplifier. These types of amplifiers are designed to offer excellent accuracy with a high level of gain and superior common-mode rejection.

The INA128U can be used in several different applications, including:

1. Medical instrumentation.

2. Industrial process control.

3. Precision data acquisition.

4. Test equipment. Some of the

key features and parameters of the INA128U are:

1. Very low offset voltage and drift.

2. High common-mode rejection ratio.

3. Wide power supply range: ±2.25V to ±18V.

To illustrate how to use the INA128U in a typical application, consider a data acquisition system.

1. Power Supply (Pin 4 and Pin 7): These pins are where the power supply is connected. Pin 4 should be connected to the negative supply voltage (Vs-) and Pin 7 to the positive supply voltage (Vs+). If the system is using a single supply, then Pin 4 should be grounded.

2. Input Terminals (Pin 2 and Pin 3): These pins are the inverting (In-) and non-inverting (In+) inputs for the amplifier. They should be connected to the differential signal that is to be amplified.

3. Output (Pin 6): The output of the INA128U is taken from this pin.

4. Gain Setting (Pin 1 and Pin 8): An external resistor (Rg) can be placed between these two pins to set the desired gain of the amplifier.

When designing a circuit with the INA128U, several key points should be kept in mind:

1. Power Supply:Ensure the power supply voltages do not exceed the INA128U's specified range. It is possible to employ a decoupling capacitor to minimize noise on the power supply lines.

2. Input Signal: The amplifier's common-mode range for the input signal must be met.

3. PCB Layout: It's crucial to have a good PCB layout to minimize noise and signal interference.

4. Thermal Considerations:Even though the INA128U is a low-power device, care should be taken to ensure adequate heat dissipation.

Always refer to the INA128U datasheet for a comprehensive understanding of its specifications and requirements. This will increase the likelihood of a successful and dependable design.
