Instructions for Using the INA128P:

1. Power Supply:

   • Ensure the supply voltage is within the range of 2.7V to 36V.
   • For optimal performance, use a stable power supply.

2. Input Connections:

   • Connect the non-inverting input (pin 2) and inverting input (pin 3) to the signals you want to amplify.
   • Use high-impedance sources to minimize loading effects.

3. Output Configuration:

   • The output (pin 6) can swing from approximately 1.5V below the negative supply to 1.5V below the positive supply.
   • Ensure the load resistance is appropriate for the output current capability.

4. Gain Setting:

   • The gain is set by the external resistor R_G connected between pins 1 and 8.
   • Gain (G) = 1 + (50 k惟 / R_G)
   • For example, to achieve a gain of 100, use R_G = 500 惟.

5. Common-Mode Rejection:

   • The INA128P has excellent common-mode rejection, but ensure that the common-mode voltage is within the specified range to avoid distortion.

6. Temperature Considerations:

   • The device is designed to operate over a temperature range of -40掳C to +85掳C.
   • Be aware of thermal considerations and provide adequate heat dissipation if necessary.

7. PCB Layout:

   • Use a ground plane to reduce noise and improve stability.
   • Keep input leads short to minimize pickup of interference.

8. Testing and Troubleshooting:

   • Verify all connections before applying power.
   • Use a multimeter to check for proper supply voltages and output levels.
   • If the output is not as expected, check the gain resistor and input signals.

By following these instructions, you can effectively use the INA128P in your applications.
