LM12L454CIV

ADCs/DACs - Special Purpose Overview

The LM12L454CIV is a specialty analog circuit manufactured by National Semiconductor, now part of Texas Instruments. It is housed in a 44-pin Plastic Quad Chip Carrier (PLCC) package with J-bend terminals and a 1.27 mm pitch. The device operates within a supply voltage range of 3 V to 5.5 V, with a nominal rating of 5 V. It functions as a 12-bit plus sign data acquisition system featuring self-calibration capabilities. The component supports industrial temperature ranges from -40°C to +85°C and is designed for surface-mount applications.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 12-bit plus sign data acquisition system
• Built-in self-calibration functionality
• Operates on single 5 V supply (3 V to 5.5 V range)
• Industrial temperature rating (-40°C to +85°C)

ADCs/DACs - Special Purpose Applications

• Precision data acquisition systems requiring self-calibration
• Industrial instrumentation with 12-bit resolution needs
• Analog signal processing circuits operating at 5 V

ADCs/DACs - Special Purpose Procurement Notes

Verify the manufacturer status, as National Semiconductor was acquired by Texas Instruments. Confirm the specific suffix 'CIV' corresponds to the PLCC-44 package and industrial temperature grade in official datasheets. Ensure compatibility with 5 V logic levels and check for any obsolete status indicators in current distributor catalogs.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a monolithic 12-bit ADC with integrated calibration is required. Compare against the LM12458 variant if higher channel counts are needed. Verify that the 44-pin PLCC footprint fits the PCB layout constraints. Ensure the application environment stays within the specified -40°C to +85°C operational range.

ADCs/DACs - Special Purpose Part Context

This part belongs to the LM12454/LM12458 family of 12-bit data acquisition systems. It shares core architecture with the LM12458 but differs in pinout or channel configuration suitable for the 44-pin LCC package. The series is characterized by its self-calibrating feature, reducing external component count for precision applications.

ADCs/DACs - Special Purpose Replacement Considerations

Check for direct equivalents in the LM12458 series if pin compatibility allows. Verify if Texas Instruments offers updated revisions of the LM12454 family. Cross-reference pinouts carefully between LM12454 and LM12458 variants before substitution.
