Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the range of 4.5V to 36V.
   • Connect the power supply to the VCC and GND pins.

2. Input Connections:

   • Connect the differential input signals to the IN+ and IN- pins.
   • For optimal performance, use a resistor (RT) between 1kΩ and 10kΩ for biasing.

3. Output Configuration:

   • The output can drive loads up to 10kΩ.
   • Ensure that the load resistance does not pull the output below -35V or above VCC-2V to avoid damage.

4. Gain Setting:

   • The AD621BR has a fixed gain of 1000 (60dB).
   • No external components are required for setting the gain.

5. Common Mode Voltage:

   • The common mode input voltage should be within the specified limits to maintain accuracy.

6. Temperature Range:

   • The device is rated for operation from -40°C to +85°C.
   • Ensure the operating environment stays within this temperature range to prevent degradation of performance.

7. Mounting and Handling:

   • Handle with care to avoid static discharge which can damage the internal circuitry.
   • Follow standard surface mount technology (SMT) procedures for mounting on PCBs.
