Part Number: OPA1652 Hi all,
I am using the OPA1652 (WSON8 package) in gain=1 configuration with +/-15V supply, and it gets quite hot; app. 40°C above ambient with idle input.
When I apply a 400kHz sine signal with +/-10V amplitude, the top case temperature…
Hi Peter-san,
Thank you for your special support. I understood that the OPA1652 simulation you would provide to me is stable with the phase margin.
Best regards, Kato

We are looking for a replacement for the OPA1678IDGKR, which we are having a lot of trouble sourcing, in a MSOP-8 (VSSOP) package, similar dimensions, 3.00mm x 3.00mm x 0.90mm…
Other Parts Discussed in Thread: OPA1652 Hi
I wish to use a OPA1652 to convert from a differential/balanced audio input to an unbalanced output (using a standard three op amp configuration as per circuit below to do this).
To ensure that the gains are…

Hi,
what do you mean by "very high failure rate"? Do you have any numbers?
