ADS1286PL

Overview

The ADS1286PL is a 12-bit analog-to-digital converter featuring a differential input and an integrated sample-and-hold amplifier. It operates with a maximum sampling rate of 20kHz and consumes only 250μA of supply current, classifying it as a micro-power device. The component utilizes an external voltage reference and communicates via a serial SPI interface. It is housed in an 8-pin PDIP package designed for through-hole mounting.

Feature Summary

• Integrates a sample-and-hold amplifier with differential input capability
• Designed for micro-power applications with low current consumption
• Supports serial SPI communication protocol

Applications

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

Procurement Notes

Verify the specific suffix 'PL' corresponds to the 8-pin PDIP package when sourcing. Confirm that the supplier provides documentation consistent with the Burr-Brown or Texas Instruments lineage, as the brand history involves corporate transitions. Ensure the component matches the 12-bit resolution and 20kHz speed specifications required by the design.

Selection Notes

Select this component when a balance between moderate resolution and ultra-low power consumption is critical. The 12-bit accuracy suits applications where high precision is not mandatory but energy efficiency is paramount. The differential input helps reject common-mode noise in electrically noisy environments.

Part Context

This part belongs to the Burr-Brown family of analog-to-digital converters, which were later integrated into Texas Instruments' portfolio. The ADS1286 series represents a line of micro-power sampling ADCs designed for battery-operated systems requiring efficient signal conversion without significant power drain.

Replacement Considerations
