We try to design a notch filter on 400Hz by ADA4077-4 but it can't work. Would you kind to give some recommendation ?Thanks.
The OP4177 is verrrrrry old; Why not use one of the newer generation parts with built in
over voltage protection, such as the ADA4077-4 or the ADA4177-4??
I would not do a new design with the OP2177. The next generation part, the ADA4077-2, is now released.
Take a look.
PS: I have read the article,
Op Amp Input Overvoltage Protection | Analog Devices
It surely lists many benefits in using ADA4177 over ADA4077 + TVS.
We are working on the HVAC solution, where we are using the CO sensing using the Figaro sensor part# TGS5342. For the same we designed the below schematic for the signal conditioning based on ADI op-amp part#ADA4077. Please help to verify the…
For the reference buffers, the primary consideration is its accuracy. You have to check the amplifier output noise, offset and drift. You don't need a high slew rate amplifier here. If I am going to suggest for the best amplifier here, it would be the…
