Overview
The LM193QT is a dual low-voltage comparator from STMicroelectronics, housed in a DFN8 2x2 package. It operates on a single supply of 2 V to 36 V or split supplies of ±1 V to ±18 V. The device features a very low supply current of 0.45 mA at 5 V and includes an input common-mode voltage range that extends to ground. Electrical characteristics include a typical input offset voltage of ±1 mV, input bias current of 20 nA, and output saturation voltage of 80 mV at 4 mA sink current. Operating temperature range spans from -55 °C to +125 °C.
Feature Summary
- Dual independent comparators designed for wide single-supply operation
- Input common-mode voltage range includes ground potential
- Low power consumption with supply current independent of voltage level
- Open-collector outputs compatible with TTL, DTL, ECL, MOS, and CMOS logic
Applications
- Basic voltage comparison circuits
- Zero crossing detectors using single power supplies
- Limit comparator configurations
- Transducer amplification stages
Procurement Notes
Verify the specific ordering code against the manufacturer's official documentation to ensure correct package type and temperature grade. Confirm that the DFN8 2x2 package variant matches the required footprint and thermal dissipation needs for the target application design.
Selection Notes
Select this component when a dual comparator with ground-referenced inputs is required within a compact surface-mount form factor. Consider the operating temperature range and supply voltage constraints relative to the system environment. Evaluate the open-collector output requirements against downstream logic interface specifications.
Part Context
This device belongs to the LM193/LM293/LM393 family of low-power, dual-voltage comparators. The LM193QT specifically denotes the industrial temperature grade version packaged in the DFN8 2x2 configuration. It shares functional similarities with other members of the series but differs in thermal performance and physical dimensions based on the selected package.
Replacement Considerations
LM293QT and LM393QT are alternative order codes within the same family offering different temperature ranges.
