we are implementing 2 to 1 multiplexing circuit using AD8180.
Application1: Toggle between 0V and 1.3V using SELECT Pin ( i.e, 0/5V TTL).
Application2: Toggle between -0.6 V and -5V using SELECT Pin ( i.e, 0/5V TTL).
In both cases we are getting zero output even with Enable pin Low (GND) and Select pin toggle between 0V and 5V.
By suspecting IC failure i have replaced with new ones.but facing same problem.
please suggest a solution.
