ADS1286U-TI

Overview

The ADS1286U is a 12-bit, micro-power sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a successive approximation architecture and features a single analog input channel. The device operates within an extended temperature range of -40°C to +85°C and is housed in an 8-pin Small Outline Integrated Circuit (SOIC) package. Key electrical specifications include a maximum conversion time of 60 µs, a maximum linear error of 0.0244%, and support for analog input voltages ranging from -5.3 V to 5.3 V. The component is lead-free and RoHS compliant.

Feature Summary

• 12-bit resolution with successive approximation architecture
• Micro-power consumption suitable for battery-operated systems
• Extended industrial temperature range (-40°C to +85°C)
• 8-pin SOIC surface-mount package

Applications

• Portable medical instrumentation
• Industrial process control data acquisition
• Battery-powered measurement devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape-and-reel quantities. Ensure the component meets RoHS compliance requirements for the target assembly process. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a 12-bit resolution and low power consumption are required for single-channel applications. The 60 µs conversion time supports moderate-speed data acquisition needs. Verify that the system voltage levels align with the specified analog input range and that the SOIC-8 footprint fits the PCB layout constraints.

Part Context

This part belongs to the ADS128x series of precision ADCs from Texas Instruments. It shares architectural similarities with other members of the family but is distinct in its 12-bit resolution and single-channel configuration. The 'U' suffix typically denotes the SOIC-8 package variant within this product line.

Replacement Considerations

Direct pin-compatible replacements within the same family may include other ADS128x variants with matching resolution and package. Verify interface compatibility and pin assignments before substituting with components from different manufacturers.
