ADS1286UA/2K5

Overview

The ADS1286UA/2K5 is a 12-bit micro-power sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a successive approximation register (SAR) architecture and features a single differential input channel. The device operates within an analog supply voltage range of 4.75 V to 5.25 V and supports digital interfaces including SPI. It offers a maximum sampling rate of 200 kSPS with a conversion time of 60 µs. The component is housed in an 8-pin SOIC package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Micro-power consumption suitable for battery-operated applications
• High-speed 200 kHz sampling capability with low latency
• Integrated programmable gain amplifier for signal conditioning

Applications

• Portable medical instrumentation
• Industrial process control systems
• Data acquisition modules

Procurement Notes

Verify the specific suffix '2K5' indicates tape-and-reel packaging containing 2,500 units per reel when sourcing. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure the ordering part number matches the required package variant and temperature grade for your design specifications.

Selection Notes

Select this component for designs requiring a balance between speed and power efficiency in a compact 8-lead form factor. Consider the SAR architecture for fast settling times compared to sigma-delta alternatives. Verify that the single-channel input configuration meets the system's multiplexing requirements without external switching complexity.

Part Context

This device belongs to the ADS128x family of precision data converters from Texas Instruments. It shares architectural similarities with other members like the ADS1286 but differs in pinout, resolution, or interface options depending on the specific model variant within the series.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative Texas Instruments ADCs with similar SAR architectures and 12-bit resolution if direct replacements are needed.
