Instructions for Using LM393DT
Supply Voltage:
- The LM393DT operates over a wide supply voltage range from 2.0V to 36.0V. Ensure the supply voltage is within this range to avoid damage to the device.
Quiescent Current:
- The quiescent current is relatively low, typically around 200μA at 5V. This makes the LM393DT suitable for battery-operated devices.
Input Offset Voltage:
- The input offset voltage should be kept within ±5mV to ensure accurate comparisons. If higher precision is required, consider using a zero-offset adjustment or a more precise comparator.
Input Bias Current:
- The input bias current is very low, typically around 0nA at 5V. This minimizes the effect of input bias currents on the circuit.
Differential Input Voltage Range:
- The differential input voltage range should not exceed the supply voltage plus 0.3V to prevent damage to the inputs.
Output Low Voltage:
- When the output is low, the voltage will be between 0.1V and 0.7V, depending on the load current. Ensure the load can handle this voltage level.
Output High Voltage:
- When the output is high, the voltage will be between 4.5V and 5.0V, depending on the load current. Ensure the load can handle this voltage level.
Output Sink Current:
- The output can sink up to 30mA when the output is low. Ensure the load does not exceed this current limit.
Output Source Current:
- The output can source up to 1.6mA when the output is high. Ensure the load does not exceed this current limit.
Response Time:
- The response time is typically around 50μs, but can range from 10μs to 100μs. This is important for applications requiring fast switching.
Handling and Storage:
- Handle the LM393DT with care to avoid static discharge, which can damage the device. Store in a dry, cool place to prevent moisture damage.
Mounting:
- Ensure proper mounting and soldering techniques to avoid thermal stress and mechanical damage. Follow the recommended PCB layout guidelines for optimal performance.
