LM10CWM

Overview

The LM10CWM is a dual operational amplifier and voltage reference integrated circuit manufactured by Texas Instruments. It features two high-performance op amps with a gain-bandwidth product of 90 kHz and a slew rate of 0.2 V/us, alongside an adjustable voltage reference. The device operates on a single supply voltage ranging from 1.1 V to 40 V, drawing only 270 uA of operating supply current per channel. It offers an input offset voltage of 2 mV, input bias current of 20 nA, and common-mode rejection ratio between 90 dB and 102 dB. The output current per channel is rated at 20 mA. It is housed in a 14-SOIC package.

Feature Summary

• Integrates dual precision operational amplifiers with an adjustable voltage reference in a single package
• Supports wide single-supply operation from 1.1 V to 40 V for flexible power management
• Provides low power consumption with 270 uA operating supply current per channel
• Delivers high common-mode rejection ratio and low input offset voltage for signal integrity

Applications

• Battery-powered instrumentation systems requiring low quiescent current
• Precision sensor signal conditioning circuits
• Industrial process control loops with wide dynamic range requirements
• Data acquisition systems needing integrated reference and amplification

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance when ordering. Confirm the SOIC-14 package variant matches your PCB footprint design. Ensure the operating temperature range meets your application's environmental constraints. Cross-reference the datasheet revision date to confirm parameter stability. Validate that the 40 V maximum supply voltage aligns with your system's power rails.

Selection Notes

Select this component when a combined op amp and voltage reference solution is needed to reduce board space. Consider the 90 kHz bandwidth for applications not requiring high-speed signal processing. Evaluate the 20 mA output drive capability against load requirements. Compare the 270 uA supply current against stricter low-power alternatives if battery life is critical. Verify the 1.1 V minimum supply voltage compatibility with your lowest power state.

Part Context

The LM10 series represents a family of monolithic operational amplifiers and voltage references designed for precision analog applications. The LM10CWM specifically denotes the commercial temperature grade version in a surface-mount SOIC-14 package. This part integrates multiple functions typically requiring separate components, simplifying circuit design for industrial and consumer electronics. It belongs to Texas Instruments' broader portfolio of mixed-signal analog devices focused on efficiency and integration.

Replacement Considerations

Check for direct pin-compatible replacements within the LM10 family, such as the LM10CN or LM10CH variants, which may offer different temperature grades or packaging options. Verify electrical parameter equivalence, particularly the gain-bandwidth product and supply voltage limits, before substituting. Consult official Texas Instruments documentation for any updated recommendations or obsolescence notices regarding legacy parts.
