Overview
The LM393DG is a dual independent precision voltage comparator manufactured by onsemi, housed in an SOIC-8 package. It operates from a wide single-supply range of 2.0 Vdc to 36 Vdc or split supplies of ±1.0 Vdc to ±18 Vdc. The device features very low current drain of 0.4 mA and low input bias current of 25 nA. Input offset voltage is specified at a maximum of 5.0 mV. The output is compatible with DTL, ECL, TTL, MOS, and CMOS logic levels.
Feature Summary
- Dual independent precision comparators designed for single or split supply operation
- Input common mode range extends to ground level
- Differential input voltage range equals the power supply voltage
- ESD clamps on inputs increase device ruggedness
Applications
- Consumer electronics
- Automotive applications
- Industrial electronics
Procurement Notes
Verify the specific ordering suffix 'DG' corresponds to the SOIC-8 Pb-Free package configuration as defined in the manufacturer's ordering information table. Confirm that the component meets RoHS compliance standards required for the intended assembly process. Ensure the procurement source provides valid traceability documentation matching the manufacturer's part number designation.
Selection Notes
Select this component when a dual comparator with rail-to-ground common-mode input capability is required. The open-collector output necessitates an external pull-up resistor for proper high-state logic generation. Verify that the application environment remains within the 0°C to +70°C operating temperature range specified for the standard grade device.
Part Context
This device belongs to the LM393 series of low offset voltage dual comparators produced by onsemi. The series includes variants such as LM293, LM2903, and NCV2903, which differ primarily in operating temperature ranges and automotive qualification status. The LM393 represents the commercial grade offering within this family.
