Replacement Transformer Started by ncag Today at 7: Product is in design stage Target: Have hooked it up as follows: Key Features Output current: ST Code of Conduct Blog. Media Subscription Media Contacts.
Limited Engineering samples available Preview: This means that the output will swing to one or the other supply rails with a miniscule input level approx. Comparator output Like many comparators, the LM has an open collector output.
Cant get pin 7 to turn on though. Product is under characterization.

LM – Voltage comparator with strobe – STMicroelectronics
In your case because of the resistor in the line for pin 3 it goes high turning of the LED. You need to reduce the gain of the circuit using Feedback.
General terms and conditions. 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? They are also designed to operate over a wide range of supply voltages: Support Center Video Center. IoT for Smart Things. Click here to register now.
Hope this helps Sandyw. Not Recommended for New Design. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Problem with LM voltage comparator.
