LTC1288IS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1288IS8#PBF is a micropower, 12-bit successive approximation analog-to-digital converter in an 8-pin SOIC package. It features a software-selectable two-channel multiplexer and operates on a single supply voltage ranging from 2.7V to 6V. The device typically draws 210μA during conversion at a sampling rate of 6.6ksps and automatically powers down to a typical leakage current of 1nA when inactive. It utilizes an external reference input and communicates via a synchronous serial interface compatible with SPI and Microwire protocols.

Analog To Digital Converters (ADC) Feature Summary

• Integrated two-channel multiplexer for flexible signal acquisition
• Automatic power-down mode reduces quiescent current to 1nA
• On-chip sample-and-hold circuitry simplifies sensor interfacing
• Serial interface supports standard microprocessor communication protocols

Analog To Digital Converters (ADC) Applications

• Pen screen digitizing systems
• Battery-operated portable instrumentation
• Remote data acquisition nodes
• Isolated data acquisition environments
• Temperature measurement circuits

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IS8 against official Analog Devices documentation to confirm industrial temperature range and SO-8 packaging specifications. Ensure compatibility with system voltage requirements between 2.7V and 6V. Confirm that the external reference configuration aligns with application needs, as the part lacks an internal reference source.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power consumption and moderate resolution in a compact footprint. The LTC1288 is suitable where a two-channel input selection is necessary without external switching components. Consider the 6.6ksps maximum sampling rate and 12-bit accuracy when designing signal conditioning stages for target sensors.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1285/LTC1288 family of 3V micropower sampling ADCs. While the LTC1285 offers a single differential input, the LTC1288 variant provides a dual-channel multiplexer. Both share identical core architecture, power characteristics, and serial interface capabilities within the same SO-8 package form factor.

Analog To Digital Converters (ADC) Replacement Considerations

LTC1285IS8#PBF serves as a functional alternative if only a single differential input channel is required, offering identical performance metrics and pinout compatibility except for the multiplexer functionality.
