ADCs/DACs - Special Purpose datasheet and documents for LM12458CIVX/NOPB
ADCs/DACs - Special Purpose Overview
The LM12458CIVX/NOPB is a mixed-signal data acquisition system integrating a 12-bit analog-to-digital converter (ADC) and a digital-to-analog converter (DAC) with self-calibration capabilities. Designed for industrial applications, it operates on a single 5V supply within the commercial temperature range of 0°C to 70°C. The device utilizes a 44-lead Plastic Quad Flatpack (PLCC) package measuring 16.66x16.66mm. It features internal signal conditioning, including an input multiplexer and programmable gain amplifier, reducing external component count for sensor interface designs.
ADCs/DACs - Special Purpose Feature Summary
- Integrated 12-bit ADC and DAC with built-in self-calibration
- Single 5V power supply operation
- Internal input multiplexer and programmable gain amplifier
- 44-lead PLCC surface-mount package
ADCs/DACs - Special Purpose Applications
- Industrial process control systems
- Data acquisition modules
- Sensor signal conditioning interfaces
ADCs/DACs - Special Purpose Procurement Notes
Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per Texas Instruments documentation. Confirm the PLCC44 package dimensions match the design footprint requirements. Ensure the operating temperature range meets the environmental specifications of the target application.
ADCs/DACs - Special Purpose Selection Notes
Select this component when a combined ADC/DAC solution with self-calibration is required for 12-bit precision. Consider the PLCC44 package constraints for PCB layout. Evaluate if the integrated PGA and MUX meet the signal chain requirements without additional external amplifiers or switches.
ADCs/DACs - Special Purpose Part Context
This part belongs to the LM12454/LM12458 family of data acquisition systems from Texas Instruments. It serves as a specialized analog circuit designed to simplify the interface between microcontrollers and analog sensors by consolidating conversion and conditioning functions into a single monolithic IC.
ADCs/DACs - Special Purpose Replacement Considerations
The LM12454 offers similar functionality with potentially different channel configurations. Verify pin compatibility and functional equivalence before substitution. Cross-reference datasheets for exact electrical parameter matching.
