Instructions for Use:

1. Power Supply Connection:

   • Connect the supply voltage (VDD) between 2.7V and 5.5V to the appropriate pins on the INA2126UA/2K5E4.

2. Input Signal Application:

   • Ensure that the input signals are within the common mode and differential input ranges to avoid damage or incorrect operation.
   • Apply the differential input signal across the input terminals, keeping within the specified differential input range.

3. Output Configuration:

   • The output can swing from 0.05V to VDD - 0.1V under a load of 10 k惟. Ensure the load resistance is within this range for optimal performance.

4. Biasing and Stability:

   • Account for the quiescent current of 130 渭A in power budget considerations.
   • Consider the input bias current when selecting external components like resistors to minimize errors.

5. Performance Optimization:

   • For best performance, especially in terms of CMRR and PSRR, operate within the specified conditions and frequencies.
   • Minimize input offset voltage effects by using proper layout techniques and shielding to reduce noise.

6. Operating Temperature:

   • Ensure the device operates within its specified temperature range to maintain reliability and performance.

For detailed specifications and advanced usage, refer to the manufacturer's datasheet.
