    INA145UA/2K5 Typical application Circuitry


    The INA145UA/2K5 is a precision unity-gain differential amplifier with high impedance inputs from Texas Instruments. It is perfect for applications requiring precise data gathering. Below are some insights on how to establish the primary connections for this IC.

    1. Power Supply: Connect V+ (pin 7) to your positive supply voltage, which can range from 2.7V to 36V. The V- (pin 4) must be attached to the circuit ground. It's crucial to remember that the input signal range should be within the supply voltage limits.

    2. Differential Input: The INA145UA/2K5 features two high-impedance inputs, IN+ (pin 3) and IN- (pin 2). The differential input signal that needs to be amplified is applied to these pins.

    3. Output: The amplified signal can be obtained from the OUT (pin 6). Remember, the output voltage will also be restricted by the supply voltage.

    4. Gain Set: Connect a resistor Kg between the pins 1 and 8 to set the gain of the amplifier. This equation can be used to calculate gain: Gain is 1 plus 100k/Kg. This allows you to adjust the amplification factor as per your requirements.

    5. Optional Connections: REF (pin 5) can be used to add an offset voltage to the output. By default, this pin should be connected to the circuit ground. For offset applications, connect a reference voltage source to this pin.

    Please remember that these instructions for connecting the INA145UA/2K5 are rather simplified. For any specific or complicated application, refer to the data sheet and application notes for the INA145UA/2K5 to get the most precise and relevant information. Proper decoupling techniques and PCB layout practices should also be followed to ensure noise-free operation.
