hi,
I'm trying to use the AD8031 as a buffer for an ADC, but it doesn't seem to be working. The op-amp is a rail-to-rail op-amp, which i am operating from 5V and ground. The ADC works ok, but when i put a buffer (voltage follower) using the adc8031 between the source and the input it stops working. The ADC is the internal adc on the pic16f690. Does anyone know why this might be happening?
