LMP7300MMX/NOPB

Overview

The LMP7300MMX/NOPB is a micropower precision single comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 12 V and consumes only 9 uA of operating current. The device features an open collector output type and delivers a response time of 7.7 us. Key electrical specifications include a maximum input offset voltage (Vos) of 750 uV, an input bias current (Ib) of 3 nA, and an input offset current (Ios) of 500 pA. Common-mode rejection ratio (CMRR) and power-supply rejection ratio (PSRR) are both rated at 80 dB. It is housed in an 8-pin VSSOP package and supports an operating temperature range from -40 C to +125 C.

Feature Summary

• Micropower operation with ultra-low quiescent current consumption for battery-powered applications
• Precision performance characterized by low input offset voltage and minimal input bias current
• Wide single-supply voltage capability supporting diverse system power architectures

Applications

• Battery-operated instrumentation systems requiring low power dissipation
• Threshold detection circuits in portable electronic devices
• Signal conditioning stages in precision measurement equipment

Procurement Notes

Verify the specific suffix MMX/NOPB against the manufacturer's official datasheet to confirm the VSSOP-8 packaging and tape-and-reel delivery format. Ensure that the open-collector output configuration aligns with your circuit's pull-up requirements. Cross-reference the RoHS compliance status directly with the component documentation provided by Texas Instruments prior to finalizing procurement orders.

Selection Notes

Select this component when design constraints demand extremely low static current draw alongside moderate precision levels. The open-collector output necessitates an external pull-up resistor, which allows flexibility in selecting the output logic voltage level independent of the supply rail. Consider the 7.7 us propagation delay as a limiting factor for high-speed switching applications where faster comparators might be more appropriate.

Part Context

This part belongs to the LMP7300 series of micropower comparators from Texas Instruments. The series is designed to bridge the gap between general-purpose comparators and high-precision operational amplifiers used as comparators. The MMX/NOPB designation indicates a specific surface-mount variant optimized for automated assembly processes in compact consumer and industrial electronics.

Replacement Considerations

Consult the Texas Instruments LMP7300 family datasheet for direct pin-compatible alternatives such as the LMP7300MA/NOPB in SOIC-8 packaging. Verify that any substitute maintains the same 2.7 V minimum supply voltage and open-collector output structure to ensure circuit compatibility without redesign.
