LM10CWM/NOPB

Overview

The LM10CWM/NOPB is a dual operational amplifier and voltage reference integrated circuit manufactured by Texas Instruments. It features two independent op-amps with a gain-bandwidth product of 90 kHz and a slew rate of 0.2 V/us. The device operates on a supply voltage range from 1.1 V to 40 V, drawing an operating supply current of 270 uA. Key electrical specifications include an input offset voltage of 2 mV, input bias current of 20 nA, and common-mode rejection ratio between 90 dB and 102 dB. Each channel provides an output current capability of 20 mA. The component is housed in a SOIC-14 package and supports surface mount installation.

Feature Summary

• Integrates dual precision operational amplifiers with a dedicated voltage reference within a single compact package
• Supports ultra-low voltage operation starting at 1.1 V for extended battery life applications
• Provides high common-mode rejection ratio to ensure signal integrity in noisy environments

Applications

• Battery-powered instrumentation systems requiring low quiescent current
• Precision sensor signal conditioning circuits
• Portable medical devices utilizing low-voltage power supplies

Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm pinout compatibility and electrical tolerances. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference RoHS compliance status directly with the latest production documentation before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require both analog signal amplification and a stable reference voltage source. The low supply voltage requirement makes it suitable for single-cell battery applications. Verify that the thermal performance of the SOIC-14 package meets the system's dissipation requirements under maximum load conditions.

Part Context

This device belongs to the LM10 series of mixed-signal integrated circuits designed for precision analog applications. It combines linear amplifier technology with bandgap reference structures. The NOPB suffix indicates lead-free construction compliant with environmental directives. This integration reduces board space compared to using separate discrete components for amplification and reference generation.

Replacement Considerations

Consult the official replacement guide for direct pin-compatible alternatives. Verify functional equivalence regarding supply voltage ranges and output drive capabilities before substitution.
