INA149: For INA149AIDR, Do we have P2P replacement material ?

Hi Xiaofu,

We do not have exact part 2 part replacement in INA149AIDR part.  INA149AIDR comes with SOIC-8 package, INA149-EP will work, but it comes with higher cost.

Depending on the type of application, INA148-Q1 (SOIC-8) or INA148 may be used, but it the common mode voltage requirements are high, then INA149 will be the only options. 

If you have additional questions, please let me know. 

Best,

Raymond
