    Hello Nomura-san, Daisuke Nomura said: Customer think that the allowable voltage range of the OPA462 is not sufficient to achieve a 300V output, is their understanding correct? The understanding is correct. OPA462 on its whole is unable to support 300V…

    Part Number: OPA462 Hi team, According to the datasheet, it seems that the output impedance just increases to about 160kOhm while the device is disabled. But are there any changes else while the device is disabled? Regards, Noriyuki Takahashi

    Hi Robert, Thank you for getting back to us regarding your findings about the OPA462 circuit. I'm glad you were able to determine that the lack of a dc path for the input is the cause of the problem. If you require any additional assistance going forward…
