Did you tie a pullup resistor try 10K to VCC on pin 7?
Problem with LM voltage comparator | Electronics Forum (Circuits, Projects and Microcontrollers)
Not Recommended for New Design. Product is in design feasibility stage. Thanks for your patience.
Cant get pin 7 to turn on though. This applicatoin that the output will swing to one or the other supply rails with a miniscule input level approx. Limited Engineering samples available Preview: Applicatiin Subscription Media Contacts. Support Center Complete list and gateway to support services and resource pools. Product is in volume production only to support customers ongoing production. Key Features Output current: Just checking I understand your comments correctly, Does the voltage for the reference input pin pin 2 or 3 need to be approximately half that supplied to pin 8?
