Part Number: OPA1S2384EVM Other Parts Discussed in Thread: OPA1S2384 Hi Jonard,
I am going to test TIA circuit using OPA1S2384.
Negative input(-IN A) is used for PD input adding R6 (0R), input(+In A) is ground.
Input signal from signal generator is 50mVpp…
Hi Jordan,
1. You are likely getting the same signal at OUTA and OUTB because amplifier B is placed in a gain of 1. To get a larger output voltage at OUTB amplifier B will need to put in to a non-inverting configuration.
2. To create a multistage gain circuit…
Hello Ian Williams,
Thank you for the support & sorry for the delay. The dark current of the existing PD is high and hence I have purchased another diode that has dark current almost 0. The application works well now. But due to ambient light/noise…
