Part Number: OPA380 Other Parts Discussed in Thread: OPA381 , OPA2383 Hi all, I was hoping to use the OPA380 (8 pin VSSOP) package for an optical sensing project. I am a bit concerned for the longevity/availability of this part. From Chat GPT discussions…
Part Number: OPA380 I need to have a TIA that can convert current for an optical detector in the range of 0.55 uA to 55 uA.
We spiced the OPA380 in our circuit and we could not get a significant voltage change with the 0.55 uA input. What part would…
Part Number: OPA380 Other Parts Discussed in Thread: OPA859 Tool/software: Hi Sir,
may we know two quesiton, and learn from you,
1. According to the reference circuit on page 11 of the datasheet, with VBIAS set to 250 mV, the output signal swing is…
Part Number: OPA380 Other Parts Discussed in Thread: OPA381 , OPA379 After installing TI PSPICE the TIA OPA380 appeared to not be part of the standard TI library ...
However, after downloading the PSPICE model from the product folder, I discovered…
Part Number: OPA380 Other Parts Discussed in Thread: OPA830 Hello,
I am currently doing an project with transimpedance amplifier for a photodioe, and I would like to test their stability. From some websites, I got an idea that I can verify this through…
Part Number: OPA380 Tool/software: Hello Experts,
Can you check this design query from customer?
"I am working with OPA380 as a current to voltage converter. The current source is BPW21R photodiode and a blue LED with wavelength 450nm to 550nm.

Other Parts Discussed in Thread: OPA380 Hello everyone,
I'am writing about simulation issue of OPA380 TI in Orcad Capture.
I tried to do simulation with pspice but the error is the following (in bold at the end):

Part Number: OPA380 Hi,
I wanted to work on OPA380 in my lab and got confused with the internal circuit given in datasheet.
I can somehow make out that bottom opamp is taking voltage of pin 2 and applying a high-pass filtering at 2.3Khz and then a…
Part Number: OPA380 Hi,
I was studying about transimpedance amp and came accross this IC. In the datasheet, there is a circuit which is intriguing me.
On the first page I came across this circuit which, as per my knowledge, is a simple transimpedance…
Part Number: OPA380 has anyone got a circuit for a transimpedance amplifier for use with a photomultiplier giving a negative output current. I should probably be able to work this out but my Texas amplifier knowledge is a bit limited :(
