LTC2472CMS#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2472CMS#TRPBF is a 16-bit delta-sigma analog-to-digital converter (ADC) from Analog Devices Inc., housed in a 12-lead plastic MSOP package. It features a fully differential input range of ±VREF and an integrated precision reference with 1.25V nominal output. The device supports selectable output rates of 208sps or 833sps via SPI interface. Electrical characteristics include a maximum offset error of 2.5mV, gain error of 0.25% of full scale, and transition noise of 3µVRMS. Supply voltage ranges from 2.7V to 5.5V, with typical conversion current of 3.5mA and sleep current of 2µA.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the C-grade designation corresponds to the 0°C to 70°C operating temperature range required for the application environment. Ensure compatibility with standard SPI interfaces regarding clock polarity and phase settings.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2472 variant specifically for differential input requirements; the LTC2470 is single-ended. Choose the CMS package for surface mount applications requiring a 12-lead MSOP footprint. Consider the 208sps rate for lower noise performance or 833sps for higher speed needs. Verify that the external RC filter values align with the low average input sampling current specification to maintain accuracy.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2470/LTC2472 family of 16-bit ADCs. The primary distinction between these models and other high-resolution converters is the proprietary input sampling scheme that significantly reduces average input current. This feature allows direct interfacing with external filters without significant error introduction, simplifying system design compared to conventional delta-sigma architectures.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. When evaluating alternatives, ensure the replacement supports differential inputs, 16-bit resolution, and compatible SPI timing specifications.
