Part Number: OPA625 Other Parts Discussed in Thread: OPA863 , OPA810 Trying to use the BOM cross tool to match up to the ADA4807-1, it came back with only the OPA625 which looks about right AC wise, but
The ADA4807-1 is +/-5V capable, while the OPA625…
Part Number: OPA625 Other Parts Discussed in Thread: DAC7811 , LM7705 , OPA837
HI. I want to use OPA625 as a current-voltage conversion circuit. If you build a circuit as shown in the figure and perform a simulation, the output voltage will be limited…
Part Number: OPA625 What would you recommend for this :-
I need a new opamp to act as a buffer before entering the ADC we use.
Need dual supply +/-5v and able to deal with its input being its rails. (Not able to stop the TIA feeding it from saturating…
Hi Manuel,
The majority of the error you are seeing is likely arising from the 100kOhm resistor you have at the non-inverting input of the OPA625. The OPA625 has a relatively large input bias current (2uA typical). If we assume a typical value then…
Hello Vlad,
The additional offset you are seeing is likely caused by the input bias current of the OPA625. The input bias current of the OPA625 has a typical specification of 2uA. Placing R1 (100ohms) in series with the input will create an additional…
Hi Tim,
Thank you for the advice. I've noticed another issue with the existing OPA625 model: the overload recovery times are much higher than what is specified in the datasheet (~300us vs. 35-50ns). I don't know if typically the model is supposed to…
Part Number: OPA863 Other Parts Discussed in Thread: OPA625 , Hello expert,
please kindly help to check replacement capability between OPA863 and LTC6246. We would like to know if OPA863 could replace LTC6246. Thanks a lot!

Part Number: OPA838 Other Parts Discussed in Thread: OPA847 , OPA2626 , OPA625 , OPA350 , OPA626 , OPA837 , OPA810 Tool/software: Hello
When I perform simulation of OPA838
The result is stable
But when I add a feedback capacitor, the circuit…
Part Number: TMS320F28379D Other Parts Discussed in Thread: OPA625 Hello,
can I connect single ended (0-3V) signal to the differential ADC Input by connecting this signal tu (+) input and GND (-) input without loosing dynamic range and 19-bit resolution…
