GPIO with no pullups or pulldowns

If switching is not something that happens during normal use, consider using a jumper, like this but use only three of the pins: Connect the centre pin to your GPIO input, and the other two outer ...

GPIO with no pullups or pulldowns

A bus-hold circuit essentially is a pull-up/-down that connects to the last known logic level. A current flows only while switching to the other state: simulate this circuit – Schematic created ...

GPIO with no pullups or pulldowns

The nRF52810 microcontroller is well-suited for the SPDT connection scheme you have come up with. It has internal programmable pull-up and pull-down resistors on its GPIO pins, so a simple procedure ...

How do the electrical characteristics of an ADC degrade over lifetime?

It'll either cost real money to get parts where this is known, or you can use some intrinsically accurate self-calibration process. A ramp from an integrator is an excellent way to check ADCs for ...

How do the electrical characteristics of an ADC degrade over lifetime?

I'm not aware of any ADCs that degrade, nor what mechanisms would lead to such (while meeting abs. max. ratings). (But then, ADCs are usually super-secret sauce, and I'm hardly expert in VLSI to ...
