Overview
The LM393WDT is a dual independent precision voltage comparator integrated circuit manufactured by ROHM Semiconductor. It operates from a single power supply ranging from +2V to +36V or split supplies of ±1V to ±18V. The device features an open-collector output, low supply current of 0.4mA typical, and input common-mode voltage range that includes ground. It supports TTL, DTL, ECL, MOS, and CMOS logic levels.
Feature Summary
- Operable with a single power supply over a wide voltage range
- Input/output ground sense capability
- Low supply current consumption
- Open collector output configuration
Applications
- Consumer Electronics
- Current Sense Application
- Battery Monitor
- Multivibrator
Procurement Notes
Verify the specific ordering suffix 'W' against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the component matches the required operating temperature range of -40°C to +85°C for the LM393 series. Confirm RoHS compliance status through the latest datasheet revision before procurement.
Selection Notes
Select this component for applications requiring dual comparators with low power consumption and wide supply voltage flexibility. The open-collector output requires an external pull-up resistor. Verify that the input common-mode voltage range meets system requirements, as it extends to ground level even with single-supply operation.
Part Context
The LM393WDT belongs to the LM393xxx family of monolithic ICs integrating two independent comparator circuits. This series is designed for high gain and low power consumption. The 'W' suffix typically denotes the SOP-J8 (Mini SO8) package variant within the ROHM product line, distinct from standard SOIC packages.
Replacement Considerations
LM2903DT: Industrial grade version with extended temperature range up to +125°C. LM339DT: Quad comparator version with similar electrical characteristics but higher supply current.
