Overview
The ADS1244IDGSTG4 is a precision, low-power, 24-bit delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single differential input channel and operates with an analog supply voltage ranging from 2.5 V to 5.25 V and a digital supply voltage between 1.8 V and 3.6 V. The device supports serial communication via I2C and SPI interfaces. It delivers a sampling rate of up to 15 SPS and includes built-in 50/60 Hz rejection capabilities. Key performance metrics include a differential nonlinearity (DNL) of +/- 1 LSB and an integral nonlinearity (INL) of +/- 0.0008% FSR. The component consumes 270 uW of power and functions within a temperature range of -40°C to +85°C, housed in a compact MSOP-10 package.
Feature Summary
- Integrated 50/60 Hz rejection filter for noise suppression
- Low power consumption suitable for battery-operated systems
- Flexible serial interface compatibility with I2C and SPI protocols
Applications
- Industrial process control systems
- Portable instrumentation devices
- Weigh scales and load cell measurements
Procurement Notes
Verify the specific suffix G4 indicates lead-free status and RoHS compliance when sourcing. Confirm the MSOP-10 package dimensions match your PCB footprint requirements. Ensure the operating voltage levels align with your system's analog and digital supply rails before integration.
Selection Notes
Select this component for applications requiring high resolution with minimal channel count. Compare against the ADS124x family variants if additional channels or different interface options are needed. Verify that the 15 SPS data rate meets the speed requirements of your specific measurement task.
Part Context
This part belongs to the ADS1244 series of precision ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS1240 and ADS1241 but is distinguished by its specific pinout, interface support, and performance characteristics tailored for single-channel high-precision applications.
Replacement Considerations
Check for direct pin-compatible alternatives within the ADS124x family. Verify electrical parameter equivalence for any substitute parts to ensure system stability.
