LTC1285CN8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1285CN8#PBF is a micropower, 12-bit successive approximation sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.7V to 6V and features an 8-lead PDIP package. The device typically draws 160μA of supply current during conversion at a sampling rate of 7.5ksps, with automatic shutdown reducing current to approximately 1nA when inactive. It includes an on-chip sample-and-hold circuit and supports serial data transfer via SPI or Microwire-compatible interfaces.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 12-bit switched-capacitor ADC with an on-chip sample-and-hold for accurate signal capture.
• Features automatic power-down mode that significantly reduces supply current between conversions.
• Supports single-ended and differential input configurations with software-selectable multiplexing options.

Analog To Digital Converters (ADC) Applications

• Battery-operated systems requiring low power consumption
• Remote data acquisition networks
• Isolated data acquisition applications
• Temperature measurement circuits

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the part marking matches the specified model number and check for RoHS compliance documentation. Ensure the packaging type corresponds to the PDIP-8 variant required for your assembly process.

Analog To Digital Converters (ADC) Selection Notes

Select this component for designs prioritizing low power consumption in portable or battery-driven applications. Consider the 12-bit resolution and 7.5ksps sampling rate for moderate-speed data acquisition tasks. Evaluate the serial interface compatibility with your microcontroller to ensure seamless integration without additional logic gates.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1285/LTC1288 family of micropower sampling ADCs. It shares architectural similarities with other 3V ADCs in the series but is distinguished by its specific pinout and input configuration. The CN8 suffix indicates a commercial temperature range and PDIP package, differentiating it from industrial grade or SOIC variants.

Analog To Digital Converters (ADC) Replacement Considerations

LTC1288CN8#PBF offers similar performance with added multiplexer functionality. LTC1286CN8#PBF provides higher speed capabilities within the same package family. Verify pin compatibility and electrical specifications before substituting to ensure system integrity.
