LTC1288IS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1288IS8#TRPBF is a micropower, 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features a two-channel multiplexer and operates on a single supply voltage ranging from 2.7V to 6V. The device typically draws 210μA of supply current when sampling at 6.6ksps and automatically powers down to a typical leakage current of 1nA during inactive periods. It utilizes an internal sample-and-hold circuit and communicates via a synchronous serial interface compatible with SPI and Microwire protocols. The component is housed in an 8-lead plastic SO package.

Analog To Digital Converters (ADC) Feature Summary

• Integrated two-channel input multiplexer for software-selectable signal acquisition
• Automatic power-down mode reduces supply current to approximately 1nA when not converting
• On-chip sample-and-hold circuitry eliminates the need for external holding capacitors
• Serial interface supports standard microprocessor communication protocols

Analog To Digital Converters (ADC) Applications

• Battery-operated portable measurement systems
• Remote data acquisition networks
• Isolated data acquisition environments
• Temperature sensing applications

Analog To Digital Converters (ADC) Procurement Notes

Verify that the IS8 suffix corresponds to the industrial temperature range (0°C to +70°C) and the TRPBF suffix indicates tape and reel packaging. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the specific ordering code matches the required package style and environmental specifications for the target design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a low pin count solution with integrated multiplexing is required for 12-bit resolution. The LTC1288 is suitable for designs where average power consumption must be minimized through duty-cycled operation. Compare against the LTC1285 if only a single differential input channel is needed, as it lacks the multiplexer but offers similar performance characteristics.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1285/LTC1288 family of 3V micropower sampling ADCs. While the LTC1285 provides a single differential input, the LTC1288 variant adds a software-configurable two-channel multiplexer. Both devices share identical core conversion architecture, power management features, and serial interface timing within the same SO-8 footprint.
