Hi..
One of the signal which is ( -3.3V to 0 ) need to clamp to level of 0V.
I can do that using the level shifter by using a voltage divider pulled up to Vref; but need to implement some other technique.
Basically I want to block (-3.3V to 0 ) range to ADC and allowing only ( 0 to +3.3VDC) signal to process.
ADC is referenced to +3.3VDC and negative reference is tied to GND internally.
Any idea or advise to work in this area?
Regards.
