ADS1201U/1K

Overview

The ADS1201U/1K is a 24-bit, low-power analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a Delta-Sigma architecture to provide high-resolution data conversion with a sampling rate of 1 kSPS. The device operates on a single 5V supply and features a serial interface for communication. Key electrical parameters include a resolution of 24 bits, an input type of differential or single-ended, and a power dissipation of approximately 8 mW at full speed. It is housed in a 16-pin SOIC package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• 24-bit resolution with no missing codes
• Low power consumption: 8 mW at 1 kSPS
• Single 5V supply operation
• Serial interface compatible with standard protocols

Applications

• Weigh scales
• Industrial process control
• Medical equipment

Procurement Notes

Verify the specific suffix '/1K' indicates reel packaging when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this component for applications requiring high precision at low data rates. Ensure the system can accommodate the serial interface timing. Verify that the external reference voltage meets the required accuracy specifications for the target application.

Part Context

The ADS1201U/1K belongs to the ADS1201 family of precision ADCs. It shares architectural similarities with other Delta-Sigma converters in the Texas Instruments portfolio but is distinct in its 24-bit resolution and 1 kSPS speed. It serves as a high-accuracy alternative to lower-resolution SAR ADCs in slow-speed measurement systems.

Replacement Considerations

Check for pin-compatible alternatives within the ADS12xx series if higher sampling rates are needed. Verify functional equivalence with other 24-bit Delta-Sigma ADCs from different manufacturers regarding interface compatibility and reference requirements.
