0 - 5 Volt sensors - Loss of resolution with 0 - 12 Volt ip?
Posted: Wed Jun 03, 2009 11:26 am
Hi,
Looking at the specifications for the analogue inputs on say the DL1 and the Dash2 I notice they have 0 - 12 volt analogue inputs.
Most of the sensors I use are 0 - 5 volt output, is there anyway to re-scale the 0 - 12 volt inputs to 0 - 5 volt?
By re-scale I mean that the internal ADC's now expect a 0 - 5 volt input to the analogue channel/s. In doing so using the full 12 bits.
I ask this because if I were to use my 0 - 5 volt sensors I would effectively be losing more half of the available 12 bit resolution that the Race Tech units have?
Just wondered what you guys do about this?
Cheers
