Other Parts Discussed in Thread: OPA132 Dear sir:
I got problem when getting the noise density plot on OPA132 with PSPICE simulation. The circuit set up and noise plot is as attached.
There's a rise on 35~40Mhz (OPA132_CIRCUIT.JPG and OPA132_NOISE_PLOT…
Other Parts Discussed in Thread: OPA132 , OPA2132 Hello!
I apologize for bad english. I am building a portable vocal speaker. I need a solution to play music from different media in MP3 and WAV format. As well as a solution for recording in WAV format on…
Hi Raymond,
Thanks for the reply.
Raymond Zhang1 said: What are the voltage rails like in your capacitive sensor application (dual or single rail)? I found the following slide, which it may help you to detect up to 2.5pF changes. Are you looking for passive…
Part Number: OPA2132 Other Parts Discussed in Thread: OPA132 Hello,
There is a phenomenon that the input bias current in the customer's OPA2132UA is increasing. Customers believe there is a place that seems to have a large leak on the board, Customers…
Part Number: OPA2132 Other Parts Discussed in Thread: OPA132 , Can you explain to me why with this type of schema, programmable via the ADG441 a gain of 1 or a gain of -1. We need to change the OPA2132U IC92 after a few months of use due to off-specification…
