Hi all,
I found the circuit below in the interweb and deiced to build it for giggles. I am using a dual BA4560 ic with the voltage divider resistors 10K each at 5VCC. The pull-up resistor is 5.1K. The trip points should be 1.66V and 3.33V
The outputs below 1.66 and 3.33 read 3V, not zero. Between 1.66 and 3.33, I do measure 5V. Any ideas why the circuit doesn't go to zero?
Thanks,
Scrib
