Overview
The ADS1245IDGSR is a low-power, 24-bit sigma-delta analog-to-digital converter manufactured by Texas Instruments. It features a single differential channel with a high-impedance buffered input and a selectable input multiplexer. The device operates on an analog supply voltage ranging from 2.5 V to 5.25 V and a digital supply voltage from 1.8 V to 3.6 V. It supports I2C and SPI interfaces for data communication. The component provides 20-bit effective resolution and includes programmable filter settings for 50 Hz and 60 Hz line frequency rejection. It is housed in a 10-pin MSOP package.
Feature Summary
- Integrates a programmable gain amplifier and a selectable input multiplexer for flexible sensor interfacing.
- Provides high-precision conversion using sigma-delta architecture with integrated noise filtering capabilities.
- Supports standard serial communication protocols including I2C and SPI for system integration.
Applications
- Industrial process control systems requiring high-resolution signal acquisition
- Weigh scales and force measurement instrumentation
- Thermocouple and RTD temperature monitoring applications
Procurement Notes
Verify the specific suffix 'G4' against the required datasheet revision when sourcing. Confirm that the operating voltage ranges align with the target system design. Ensure the MSOP-10 package footprint matches the PCB layout specifications. Check for availability as this part number may have lifecycle status variations compared to non-suffix variants.
Selection Notes
Select this component for applications demanding high resolution at low sampling rates. It is suitable where power consumption is critical but precision is paramount. Consider the external reference requirement and the need for multiplexing inputs. Evaluate the trade-off between the 24-bit specification and the effective 20-bit resolution for cost-sensitive designs.
Part Context
This device belongs to the ADS124x family of precision ADCs from Texas Instruments. It shares pin compatibility with the ADS1244, differing primarily in the inclusion of an internal multiplexer. The series is designed for low-power, high-accuracy measurements in battery-operated or energy-constrained environments.
Replacement Considerations
The ADS1245IDGST is a direct substitute offering identical functionality in a tape-and-reel compatible package format. Verify that the mechanical dimensions and lead finish meet the assembly requirements before substitution.
