Instructions for LM393ADT
Supply Voltage Connection:
- Connect the supply voltage (Vcc) to pin 8 and ground (GND) to pin 4. Ensure the supply voltage is within the operating range of 2.0V to 36.0V.
Input Signal Application:
- Apply the input signals to pins 2 (IN-) and 3 (IN+). The differential input voltage should not exceed 300mV to avoid damage or incorrect operation.
Output Configuration:
- The output is open collector, requiring a pull-up resistor to a suitable voltage level. For typical operation, use a pull-up resistor to Vcc.
- When the voltage at IN+ is higher than IN-, the output will be low (typically around 0.4V when sinking 4mA).
- When the voltage at IN- is higher than IN+, the output will be high (Vcc - 1.5V).
Quiescent Current Consideration:
- The quiescent current is typically 80μA at 5V supply. Design your power supply system considering this consumption.
Handling and Storage:
- Handle with care to avoid electrostatic discharge (ESD) damage. Store in an ESD-safe environment when not in use.
Thermal Considerations:
- Ensure adequate heat dissipation if used in high ambient temperatures or high-power applications.
