LMC6953CMX

Supervisors Overview

The LMC6953CMX is a dual operational amplifier manufactured by Texas Instruments, belonging to the LMC695x series. It features rail-to-rail input and output capabilities, allowing operation with supply voltages ranging from 2.7V to 16V. The device offers a gain-bandwidth product of 4MHz and a slew rate of 3V/µs. Designed for low-power applications, it draws a quiescent current of 800µA per channel. The component is housed in an 8-SOIC package (0.154 inch width) and operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Rail-to-rail input and output functionality enables full signal swing across the entire supply voltage range.
• Low power consumption with a quiescent current of 800µA per channel supports battery-operated systems.
• High speed performance characterized by a 4MHz gain-bandwidth product and 3V/µs slew rate.

Supervisors Applications

• Portable instrumentation requiring high accuracy and low power
• Active filters and signal conditioning circuits
• Battery-powered medical devices

Supervisors Procurement Notes

Verify the specific suffix 'CMX' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the operating environment remains within the specified -40°C to +85°C commercial temperature range. Ensure supply voltage does not exceed the maximum rating of 16V to prevent device damage. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Supervisors Selection Notes

Select this component when both rail-to-rail I/O and moderate speed are required simultaneously. It serves as a suitable alternative to higher-speed op-amps where power efficiency is critical. Consider the 8-SOIC package constraints for PCB layout. Evaluate thermal dissipation requirements if multiple units operate at maximum load within the enclosed space.

Supervisors Part Context

The LMC6953CMX is part of the LMC695x family of dual operational amplifiers. This series is designed to provide cost-effective solutions for general-purpose analog signal processing. The CMX designation indicates the surface-mount SOIC package configuration. It complements single-channel variants like the LMC6952 for differential or multi-stage designs.

Supervisors Replacement Considerations

Check for direct pin-compatible replacements such as other LMC695x variants or equivalent rail-to-rail dual op-amps from other manufacturers. Verify that substitute components meet the same 4MHz bandwidth and 800µA quiescent current specifications. Ensure the replacement package matches the 8-SOIC footprint for board compatibility.
