I need to convert FPGA output to +/- 2.5V differential. i am going to use 8BIT DAC to get the signal in analog domain..but not sure what I can do to get the analog differntial signal? Any help please!!
dac in some ways like 1. pwm with resistor capacitor
2. resistor ladder network
and then use any opamp, i hope there is a comparator in your design also at starting for range select
