Overview
The LM193H/NOPB is a dual low-power, low-offset voltage analog comparator manufactured by Texas Instruments. It features an 8-pin TO-99 metal can package designed for through-hole mounting. The device operates on a single or split power supply ranging from 2 V to 36 V. Key electrical specifications include a maximum input offset voltage of 2 mV and a typical quiescent current of 500 µA per channel. It provides a propagation delay of 1.3 µs and supports output currents up to 6 mA. The component functions reliably within an extended temperature range of -55°C to 125°C.
Feature Summary
- Dual-channel architecture with low offset voltage characteristics
- Low power consumption suitable for battery-operated systems
- Wide single-supply operating voltage range
- CMOS and TTL compatible output types
Applications
- Precision voltage monitoring circuits
- Threshold detection systems
- Battery-powered instrumentation
- Industrial control logic interfaces
Procurement Notes
Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence during procurement. Confirm the package type matches the required 8-TO-99 form factor for your PCB layout. Ensure the manufacturer source is authorized to guarantee authenticity. Cross-reference the datasheet revision date to confirm parameter consistency. Validate that the operating temperature range meets your environmental requirements.
Selection Notes
Select this component when low offset voltage and low power consumption are critical design constraints. The wide supply voltage range allows flexibility in system power architecture. Consider the TO-99 package size if space permits and hermetic sealing or robust mechanical stability is needed. Compare propagation delay specifications against other comparators if high-speed switching is required. Evaluate thermal performance within the specified temperature limits.
Part Context
The LM193 series represents a family of dual differential input voltage comparators designed for single-supply operation. The LM193H/NOPB variant specifically targets applications requiring low offset voltage and low power dissipation. It shares functional similarities with the LM293 and LM393 but offers distinct performance characteristics in offset and power metrics. The device is part of Texas Instruments' broader portfolio of linear integrated circuits.
Replacement Considerations
Public confirmed substitute part numbers include LM193H and LM193JAN. Verify pinout compatibility and electrical parameter overlaps before substitution. Ensure the replacement part meets the same package and temperature requirements.
