Hello,
I'm building a dual purpose 0..20mA 0..10V to 0..5V circuit to connect sources to ADC.
It also features protection.
I've simulated it and it seems to work correctly.
I'm not sure about filters cap, they should go up to 10k without problems.
R6 will be 51k + 2k2 in real implementation, and R2 will be 500.
Also the opamp MCP6001 or dual or quad version depending on how many input I need.
It is designed to be attached to a ADS1115, so I think I'll go for MCP6004.
Simulated diode are BAS40, I think I'll go for BAS70.
Attached the LTSpiece simulation source and and a simulation image.
Do you have any suggestion?
