LMV762MMX

Overview

The LMV762MMX is a dual-channel precision analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5 V and consumes 450 uA of quiescent current. The device features a push-pull output stage with a response time of 120 ns. Key electrical parameters include an input offset voltage of 1 mV, input bias current of 50 pA, and input offset current of 5 pA. Common-mode rejection ratio is 100 dB, while power supply rejection ratio reaches 110 dB. It functions in temperatures from -40°C to +125°C and is housed in an 8-pin VSSOP package.

Feature Summary

• Dual-channel configuration providing two independent precision comparators in a single compact package.
• Push-pull output architecture enabling direct interfacing with digital logic circuits without external pull-up resistors.
• Low quiescent current consumption designed for efficient operation in battery-powered or energy-constrained systems.
• High common-mode rejection ratio ensuring accurate signal comparison despite noise on the input lines.

Applications

• Battery-operated portable devices requiring low-power signal monitoring
• Threshold detection circuits in industrial control systems
• Voltage level shifting between different logic families
• Simple over-voltage or under-voltage protection schemes

Procurement Notes

Verify the specific suffix 'MMX' corresponds to the tape-and-reel packaging format when ordering. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance if required by your assembly process. Ensure the VSSOP-8 footprint matches your PCB layout constraints. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a dual-channel solution is needed with strict low-power requirements. The 120 ns propagation delay suits moderate-speed applications but may be insufficient for high-frequency signaling. Consider the 1 mV offset voltage tolerance for precision requirements. The VSSOP-8 package offers space savings compared to larger DIP options. Verify thermal performance within the specified operating temperature range for your enclosure design.

Part Context

This part belongs to the LMV762 series of low-voltage precision comparators. It shares functional similarities with other members of the family but differs in packaging and reel specifications. The MMX suffix specifically denotes the surface-mount VSSOP-8 variant supplied in reels. It serves as a cost-effective alternative to higher-speed comparators where precision and power efficiency are prioritized over switching speed.

Replacement Considerations

LMV762MM/NOPB is a verified equivalent offering identical electrical characteristics in a tube-packaged VSSOP-8 form factor. LMV762QMM/NOPB provides automotive-grade qualification with similar pinout but higher quiescent current. Check datasheets for any differences in output drive capability or thermal resistance before substituting.
