I was looking at the datasheet for the LTC-4627JR, and it looks like each digit shares a common anode, and each segment shares a common cathode.
My question is given this configuration, I don't understand how to drive each digit separately.
For example, say I want
digit 1, segment A and
digit 2, segment B to be on, with everything else off.
I could attach
pin 1 and
pin 2 to Vcc to enable the two digits, but if I try to connect
pin 14 to ground (through a resistor, of course), this will turn segment A on for both digit 1 and digit 2. Likewise, trying to connect
pin 16 to ground, this will turn segment B on for both digits.
Is there something I'm missing here? Or is this how this display is intended to work?
This is similar to this question, but as far as I can tell the answers to that question doesn't allow powering all digits differently from each other.
