Part Number: OPA381 Hi,
I am trying to detect the DLP white Pulse through photodiode (#PD438C/S46) but DLP signals are not detected when ambient light is ON.
Here is the circuit that i am using
Here is graph when t he input data is in black/green colour…
Happy New year, Kai!
Of course, 25mV vs 0.025mV is typo. But my comment was about something else. I would like to return to the original message (Dec 23, 2019 1:22 PM). There is a contradiction in the documentation for two similar TIOA: OPA380 & OPA381…
Part Number: OPA381 Other Parts Discussed in Thread: INA381 Hi team,
A customer wants to use the input of OPA381 for overload detection and would like to delay it with an RC filter (switch-on pulses etc). For that they would like to know how much current…
Part Number: OPA381 Other Parts Discussed in Thread: OPA4388 , OPA2378 Hello everyone,
I would like to amplify signals from an array of photodiodes that are internally connected in a common cathode fashion.
This makes the commonly seen photoconductive …
Part Number: OPA381 Referencing a circuit like that in Figure 3 of the OPA381 datasheet, is there any reason I cannot tie the anode of the photodiode to a -10V bias instead of ground? I understand I will have a higher dark current but I need to lower…
Part Number: OPA381 Hi!
I'm trying to make some optical head with diode laser and OPA381 trans-impedance amplifier. Parameters of laser diode direct me to use 6v supply.
Is it safe to apply it to OPA381 without any sufficient degradation of its parameters…
Part Number: OPA381 Other Parts Discussed in Thread: LM7705 Support Path: /Product/Help with Device Selection/ Sometimes ago I used OPA381 as Transimpedance Ampli for OSRAM PD BPW34. I like an option of OPA381 "swing to ground" by ext. resistor.…
Part Number: OPA830 Other Parts Discussed in Thread: OPA381 , TINA-TI , OPA392 Hello community,
I have designed a strain gauge sensor using OPA381 in a bridge configuration in TINA-TI (attached herewith), taking reference from the application circuit of…
Hi Jim,
Glad I could help resolve this OPA381 application. And thanks to Kai for his inputs!
I'll close this one out.

Thanks Nick, that didn't fix it though. New models/libraries downloaded, but available device list still reads ...OPA379, OPA381 ...
PSPICE just seems to ignore the OPA380 lib files(?)
