Overview
The LM3302DR is a quad differential analog comparator manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It operates on a single supply voltage ranging from 2 V to 28 V with a typical operating supply current of 16 mA. The device features CMOS and TTL compatible outputs and delivers a response time of 300 ns. Key electrical specifications include an input offset voltage of 20 mV, an input bias current of 500 nA, and an input offset current of 100 nA. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates four independent differential comparators into a single compact package for space-constrained designs.
- Provides output compatibility with both CMOS and TTL logic families for versatile interfacing.
- Operates reliably across a wide single-supply voltage range without requiring shutdown functionality.
Applications
- General-purpose signal comparison circuits
- Voltage monitoring systems
- Threshold detection applications
Procurement Notes
Verify the specific suffix 'DR' corresponds to the SOIC-14 package and tape-and-reel shipping configuration as documented in official Texas Instruments ordering information. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the selected distributor sources directly from authorized channels to guarantee authenticity and traceability of the semiconductor material.
Selection Notes
Select this component when a quad comparator solution is required with low power consumption and broad supply voltage flexibility. The 300 ns response time suits general-purpose applications rather than high-speed signaling. Consider the SOIC-14 footprint for PCB layout constraints. Verify that the 20 mV input offset voltage meets the precision requirements of the specific circuit design.
Part Context
This part belongs to the LM3302 series of analog comparators produced by Texas Instruments. It is categorized under linear integrated circuits and amplifier ICs. The device serves as a standard general-purpose comparator alternative in mixed-signal electronic designs, offering a balance between performance and cost-effectiveness for industrial and consumer electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official manufacturer cross-reference guides for potential equivalents.
