LPV7215MGX/NOPB

Overview

The LPV7215MGX/NOPB is a single-channel analog comparator manufactured by Texas Instruments, part of the LPV7215 series. It operates within a supply voltage range of 1.8 V to 5.5 V and consumes a maximum quiescent current of 750 nA. The device features rail-to-rail input and output capabilities with a push-pull configuration. Key electrical specifications include a maximum input offset voltage of 3 mV at 5 V, an input bias current of 0.4 pA, and a typical common-mode rejection ratio of 98 dB. It supports a maximum output current of 19 mA and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Ultra-low power consumption with a maximum quiescent current of 750 nA for battery-operated applications
• Rail-to-rail input and output capability allowing full signal swing near supply rails
• High precision performance characterized by low input offset voltage and minimal input bias current
• Robust noise immunity provided by high common-mode rejection and power supply rejection ratios

Applications

• Wearable photovoltaic ultra-low frequency acupoint stimulators
• Low voltage general-purpose signal conditioning circuits
• Battery-powered sensor interface modules

Procurement Notes

Verify the specific suffix 'MGX' against the manufacturer's official documentation to confirm the SC-70-5 package and tape-and-reel shipping format. Ensure the component meets RoHS3 compliance requirements as indicated in standard datasheets. Cross-reference the ordering number with authorized distributors to validate availability and authenticity before procurement.

Selection Notes

Select this component when design constraints require extremely low static current combined with rail-to-rail signal handling in a compact SC-70-5 footprint. It serves as a suitable alternative to higher-power comparators in space-constrained portable devices. Verify that the 1.8 V minimum supply voltage aligns with the system's power architecture and that the 19 mA drive capability meets load requirements.

Part Context

This device belongs to the LPV7215 family of low-power, rail-to-rail comparators from Texas Instruments. It shares functional similarities with the LMV7215 and LMC7215 series but offers distinct performance characteristics regarding input bias current and supply voltage ranges. The MGX variant specifically denotes the SC-70-5 surface-mount package configuration optimized for high-density PCB layouts.

Replacement Considerations

The LPV7215MFX/NOPB (SOT-23-5 package) is a pin-compatible alternative within the same family. The LMV7215 series may serve as a substitute if slightly higher quiescent current is acceptable. Verify package dimensions and thermal characteristics when substituting between SOT-23-5 and SC-70-5 form factors.
