ADS1286UA/2K5G4

Overview

The ADS1286UA/2K5G4 is a 12-bit micro-power sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes successive approximation architecture and features a single differential input channel with an SPI-compatible serial interface. The device operates on a unified analog and digital supply voltage ranging from 4.5 V to 5.25 V, consuming 1.25 mW of power at a maximum sampling rate of 20 kS/s. It provides integral nonlinearity of ±2 LSB and differential nonlinearity of ±1 LSB, achieving a signal-to-noise and distortion ratio of 72 dB. The component is housed in an 8-pin SOIC package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

Micro-power consumption design suitable for battery-operated applications
Single-channel differential input configuration for noise rejection
SPI-compatible serial interface for simplified system integration

Applications

Portable medical instrumentation
Industrial process control systems
Data acquisition modules

Procurement Notes

Verify the specific suffix against official documentation to confirm packaging format and environmental compliance status. Ensure the ordering part number matches the required tape-and-reel quantity specifications defined by the manufacturer. Cross-reference the datasheet revision date to validate parameter accuracy before final procurement decisions.

Selection Notes

Select this component when a 12-bit resolution is sufficient for the application requirements. Consider the 20 kS/s sampling limit and SOIC-8 package constraints during PCB layout. Verify that the external reference voltage source meets the stability requirements for the specified linearity performance.

Part Context

This device belongs to the ADS1286 family of micro-power ADCs from Texas Instruments. It shares architectural similarities with other members in the series but is distinguished by its specific 12-bit resolution and single-channel configuration. The family targets low-power data conversion needs in compact form factors.
