LMV7235M7X/NOPB

Overview

The LMV7235M7X/NOPB is a single-channel, ultra-low power, low voltage comparator manufactured by Texas Instruments. It features rail-to-rail input capability and an open-drain/push-pull output configuration. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V. Key electrical specifications include a maximum propagation delay of 62 ns, a typical common-mode rejection ratio (CMRR) of 67 dB, and a typical power supply rejection ratio (PSRR) of 85 dB. The input bias current is specified at 0.4 µA at 5 V, with a maximum input offset voltage of 6 mV at 5 V. The static supply current is limited to 95 µA. It is housed in a compact SC-70-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Ultra-low power consumption with a maximum static supply current of 95 µA
• Rail-to-rail input stage allowing full signal swing utilization
• Flexible output architecture supporting both open-drain and push-pull configurations
• High precision performance with low input offset voltage and high CMRR

Applications

• Battery-powered portable electronic devices requiring minimal quiescent current
• Low voltage signal conditioning circuits
• Threshold detection systems in consumer electronics
• General-purpose analog comparison tasks in space-constrained designs

Procurement Notes

Verify the specific suffix M7X against the manufacturer's official datasheet to confirm the tape-and-reel packaging format and quantity per reel. Ensure the component meets RoHS3 compliance requirements as indicated in the documentation. Cross-reference the ordering part number with the distributor's catalog to confirm availability and lead times prior to procurement. Confirm that the SC-70-5 footprint matches the design layout constraints.

Selection Notes

Select this component when designing for environments where power efficiency is critical alongside moderate speed requirements. The rail-to-rail input feature makes it suitable for applications utilizing low-voltage signals near ground or supply rails. Consider the open-drain output option if interfacing with different logic voltage levels is required. The small SC-70-5 package is ideal for dense PCB layouts. Evaluate the 62 ns propagation delay against system timing requirements to ensure adequate response speed.

Part Context

This device belongs to the LMV723x family of comparators from Texas Instruments, designed for low-voltage, low-power applications. The family includes variants with different channel counts and output types. The LMV7235 specifically offers a single channel with versatile output options. It serves as a modern replacement for older bipolar comparators in battery-operated systems, offering significantly lower power consumption while maintaining sufficient speed for general-purpose applications.

Replacement Considerations

Check for direct pin-compatible alternatives within the LMV723x series, such as the LMV7235M5/NOPB, which shares similar electrical characteristics but may differ in packaging. Verify that any substitute maintains the same supply voltage range, input offset voltage limits, and propagation delay specifications to ensure circuit compatibility without redesign.
