Hi there!
I have some 3.3V sensors with analog outputs that I would like to interface to a 5V ADC converter, while maintaining full resolution. ie, I don't want to just give up the range of digital values generated between 3.3V an 5V. An example of one of these sensors is a 3 axis accelerometer, with an analog output for each axis. You can view the data sheet here:
The ADC expects a value between 0 and 5V volts (analog), so if I just send in the 3.3Vmax signal, I'll be wasting valuable resolution. How can I proportionally amplify the 3.3V sensor output so it ranges from 0 to 5V?
Thanks so much!!!
