ADS1210UG4

Overview

The ADS1210UG4 is a 24-bit analog-to-digital converter (ADC) manufactured by Texas Instruments, housed in an 18-pin Small-Outline Package (SOP). It utilizes sigma-delta architecture to achieve high resolution with a maximum data rate of 16 kilospamples per second. The device operates on a single supply voltage ranging from 4.75 V to 5.25 V and supports differential input signals. Key integrated features include a programmable gain amplifier and an internal reference voltage source. The component is designed for industrial applications within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates a programmable gain amplifier and internal reference voltage to minimize external component requirements.
• Employs sigma-delta modulation architecture to deliver high-resolution 24-bit conversion capabilities.
• Supports flexible digital interface communication protocols including SPI and I2C for system integration.

Applications

• Industrial process control systems requiring precise sensor signal acquisition
• High-resolution weighing scales and load cell measurement interfaces
• Medical instrumentation devices demanding low-noise analog front-end processing

Procurement Notes

Verify the specific package variant and suffix designation against the manufacturer's current product status documentation. Confirm that the ordering information matches the required pinout and thermal specifications for the target PCB layout. Ensure compliance with relevant environmental directives such as RoHS standards before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require high-resolution data acquisition with minimal external calibration. Consider the trade-off between the maximum 16 kSPS data rate and the available filter settings. Evaluate the power consumption characteristics against the system's battery life or thermal management constraints during operation.

Part Context

This part belongs to the ADS121x family of precision analog-to-digital converters from Texas Instruments. It shares architectural similarities with the ADS1211 but differs in pin count and channel configuration. The UG4 suffix indicates a lead-free and RoHS-compliant manufacturing version of the standard ADS1210U device.

Replacement Considerations

The ADS1211U serves as a functional alternative within the same family, offering similar performance metrics with additional input channels. Verify pin compatibility and software register configurations when substituting these components in existing designs.
