LTC1286IS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1286IS8#TRPBF is a micropower, 12-bit successive approximation analog-to-digital converter (ADC) in an 8-lead SOIC package. It features a single differential analog input and operates on a single supply voltage ranging from 4.5V to 9V. The device typically draws 250µA of supply current when sampling at 12.5ksps and automatically powers down to a typical leakage current of 1nA during idle periods. It includes an on-chip sample-and-hold circuit and communicates via a serial interface compatible with SPI and Microwire protocols.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the IS8 designation corresponds to the industrial temperature range (-40°C to +85°C) and the SOIC-8 plastic package. Ensure compatibility with the required supply voltage range of 4.5V to 9V for the specific application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power consumption and high input impedance without external gain stages. The LTC1286 is suitable for ratiometric applications or use with an external reference. Note that the LTC1298 variant offers a 2-channel multiplexer but is limited to a 4.5V to 5.5V supply range, whereas the LTC1286 supports up to 9V.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1286/LTC1298 family of micropower sampling ADCs. The LTC1286 specifically provides a single differential input, while the LTC1298 provides a software-selectable 2-channel multiplexer. Both share similar architectural features but differ in input configuration and maximum supply voltage specifications.
