HI HUNTER63

CONGRATULATION VERY NICE JOB

[Detectorist#1]

And what is the final schematic of this beautiful board?

[hunter63]

Hello
I will post the corrected documentation after the PCB is launched, at the moment I am at the stage of ordering the PCB production, best regards

Hello, I am looking for a replacement forLF442-MIL Dual Low Power JFET Input Operational Amplifier in the SMD version

[Altra]

The LMC6482 is a good choice

[Nightryder]

Can not wait. all the best

[Detectorist#1]

Hi Altra,
LMC6482 is very good choice for sample-hold stage but too noisy choice for input stage.

[Altra]

Okay you didn't mention front end. OPA1612,

[Detectorist#1]

Yes, Altra,
OPA1612 is one of the best OpAmps for front end of PI MD, especially if input stage is non-inverting and input resistor on positive input is under 1KoHm and input resistor in negative input is from 2.2 to 100 oHms.
