Overview
The LM393BIDSGR is a dual differential analog comparator from the Texas Instruments LM393B series, housed in an 8-pin VSSOP package. It operates on a single supply voltage ranging from 2V to 36V, with typical testing at 30V. The device features a low quiescent current drain that remains independent of the supply voltage. Key electrical parameters include a maximum input offset voltage of 0.37mV and an ESD rating of 2kV (HBM). The output type is open collector, compatible with CMOS and TTL logic families.
Feature Summary
- Dual differential comparators designed for single-supply operation across a wide voltage range
- Low input offset voltage specification ensuring high precision comparison
- Open-collector outputs providing flexibility for various logic interface requirements
- Enhanced electrostatic discharge protection rated at 2kV using human body model
Applications
- Commercial-grade voltage monitoring circuits
- Threshold detection systems requiring precise voltage comparison
- General-purpose analog signal processing applications
Procurement Notes
Verify the specific B-version suffix against the manufacturer's latest documentation to confirm updated specifications such as the 0.37mV offset voltage and 38V maximum rating. Ensure the VSSOP-8 package matches the design footprint. Confirm RoHS compliance status through official datasheets before finalizing procurement plans.
Selection Notes
Select this component when high precision is required due to its improved 0.37mV input offset voltage compared to standard versions. The wide supply voltage range up to 36V makes it suitable for diverse power environments. The open-collector output allows easy interfacing with different logic levels without additional level shifting components.
Part Context
This part belongs to the LM393 family of dual comparators, specifically the commercial-grade B-version variant. It shares functional similarities with the LM2903B and LM193 but offers enhanced performance metrics. The LM393BIDSGR represents an evolution in the series with improved electrical characteristics while maintaining the industry-standard pinout and functionality.
Replacement Considerations
Compatible substitutes include the LM2903BIDSGR and LM193IDSGR, which share similar dual-comparator architectures. Verify pin compatibility and electrical parameter alignment, particularly the input offset voltage and supply voltage limits, before implementing any cross-references.
