I would like to use an LM3914 display driver to monitor the outputs from sensors that have a range from 0.1 to 0.9 volts so in simple terms a 0.0 to 1.0 volt readout in steps of 0.1 volt would be ideal.
I can find plenty of information on using the LM3914 for expanded ranges that are well above the internal reference source -there are examples in the National Semiconductor data sheet itself- but nothing about expanded range displays for small voltages.
I would be grateful for any guidance as to how the job can be done and an idea of how to calculate the required component values.
Thank you.
