ADS1244IDGST

Overview

The ADS1244IDGST is a single-channel, 24-bit delta-sigma analog-to-digital converter manufactured by Texas Instruments. It operates with an analog supply voltage range of 2.5 V to 5.25 V and a digital supply voltage range of 1.8 V to 3.6 V. The device supports sampling rates up to 15 S/s and features differential or single-ended input types. It utilizes an SPI interface for communication and is housed in a 10-lead MSOP package. 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.

Feature Summary

• Integrated 50/60 Hz rejection capability for noise suppression
• Low-power sigma-delta architecture for energy-efficient operation
• External reference input support for flexible system design

Applications

• Low-power embedded systems requiring high-resolution data acquisition
• Industrial process control instrumentation
• Precision weighing scales and load cell measurements

Procurement Notes

Verify the specific suffix IDGST corresponds to the MSOP-10 package and commercial temperature grade when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure external reference circuitry matches the specified voltage requirements for optimal linearity performance.

Selection Notes

Select this component for applications demanding high resolution at low data rates. The 24-bit resolution and low noise characteristics make it suitable for sensor interfaces where signal integrity is critical. Consider the separate analog and digital supply domains for proper grounding strategies in mixed-signal designs.

Part Context

This part belongs to the ADS1244 series of precision ADCs from Texas Instruments. It is designed specifically for applications requiring high accuracy and low power consumption. The device integrates a programmable gain amplifier and a stable internal reference option, though external references are supported for enhanced performance.

Replacement Considerations

Check for pin-compatible alternatives within the same family if package availability is constrained. Verify that substitute parts maintain the 24-bit resolution and 15 S/s sampling rate specifications.
