Overview
The LM393 MDC is a dual voltage comparator manufactured by Texas Instruments. It features low supply current consumption and an output stage compatible with TTL, CMOS, or MOS logic. The device operates from a single power supply or split supplies. Key electrical parameters include a typical offset voltage of 2 mV and a common-mode input voltage range that includes ground. The output can be pulled up to any voltage within the supply range.
Feature Summary
- Low supply current consumption
- Output compatible with various logic families
- Common-mode input voltage range includes ground
Applications
- Precision rectifiers
- Active filters
- Peak detectors
Procurement Notes
Verify the specific suffix 'MDC' against official Texas Instruments documentation to confirm package type and temperature grade. Ensure compatibility with required operating conditions before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when low power consumption and ground-referenced input are critical. Consider the open-collector output requirement for proper interfacing with downstream logic circuits. Evaluate thermal performance if operating near maximum ratings.
Part Context
This part belongs to the LM393 family of dual comparators. It is widely used in industrial and consumer electronics where cost-effective comparison functions are needed. The MDC suffix typically denotes a specific package configuration and manufacturing lot tracking.
Replacement Considerations
Check for direct pin-compatible replacements such as other LM393 variants. Verify electrical specifications match original requirements. Consult manufacturer substitution guides for validated alternatives.
