OPA1652: OPA1652AIDR no output

Part Number: OPA1652
There is no output when testing on the machine, what is the reason?
  • Hello, 

    In order to assist I would need a schematic of the test circuit configuration including component values, supply voltage, common mode voltage and the applied test voltage at the input. Alternatively an equivalent circuit can be made in Tina or PSpice to show here for guidance on the issue. A schematic can be provided privately by using the friend request feature on the E2E if it cannot be posted here. A private message can be shared after the friend request is established. 

    You may check to see if

    • The linear input common mode voltage condition is being violated, this can cause the amplifier's output to rail out. 
    • One or both inputs, or output may be floating from a bad solder joint
    • Check for oscillations on the output indicating instability 

    There are several things that can cause issues. Any additional information you can provide to help us understand the issue further would be helpful. 

    Best Regards,
