Overview
The ADS1244IDGSR is a 24-bit Delta-Sigma analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 15 SPS and features integrated 50/60 Hz rejection capabilities. The device supports differential and single-ended inputs within an MSOP-10 package. Analog supply voltage ranges from 2.5 V to 5.25 V, while digital supply voltage spans 1.8 V to 3.6 V. Power consumption is specified at 270 uW. Nonlinearity performance includes DNL of +/- 1 LSB and INL of +/- 0.0008% FSR. The operating temperature range extends from -40 C to +85 C.
Feature Summary
- Integrated 50/60 Hz line frequency rejection for noise suppression
- Sigma-Delta architecture providing high resolution data conversion
- Supports both differential and single-ended input configurations
Applications
- Precision weighing scales
- Industrial process control systems
- Medical instrumentation
Procurement Notes
Verify the specific suffix IDGSR against official datasheets to confirm the reel packaging variant. Ensure compatibility with SPI interface requirements and power supply specifications during sourcing. Cross-reference manufacturer part numbers to avoid counterfeit components.
Selection Notes
Select this component when high-resolution 24-bit accuracy is required at low sampling speeds. Consider the integrated filter characteristics for applications sensitive to power line interference. Verify that the MSOP-10 package fits the available PCB footprint constraints.
Part Context
This model belongs to the ADS1244 series of precision ADCs. It shares architectural similarities with other devices in the family but offers specific pinout and performance characteristics defined by the IDGSR designation. It serves as a specialized solution for low-speed, high-accuracy measurement tasks.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official Texas Instruments resources for potential cross-references or updated revisions before substituting.
