LTC1197LCS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1197LCS8#PBF is a 10-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices. It features a sampling rate of up to 500ksps and operates on a single supply voltage ranging from 2.7V to 4V. The device utilizes an external voltage reference and supports differential or single-ended input configurations. Power dissipation is typically 2.2mW at 2.7V during full-speed operation, with automatic shutdown reducing power consumption linearly at lower sample rates. It is housed in an 8-lead MSOP package.

Analog To Digital Converters (ADC) Feature Summary

• 10-bit resolution with a maximum sampling rate of 500ksps
• Low power consumption: 2.2mW typical at 2.7V; 25mW typical at 5V
• Auto Shutdown feature reduces power linearly as sample rate decreases
• SPI and Microwire compatible serial I/O interface

Analog To Digital Converters (ADC) Applications

• Battery-powered instrumentation systems
• Portable data acquisition devices
• Industrial process control loops
• Medical monitoring equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'LCS8' against official Analog Devices documentation to confirm pinout and thermal characteristics for the MSOP package. Ensure the design accommodates the required external reference voltage and serial communication timing constraints specified in the datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate resolution (10-bit) and high speed (500ksps) is required in a low-power application. Compare against the LTC1196 series if 8-bit resolution suffices for further cost reduction. Verify that the system's available supply voltage falls within the 2.7V to 4V range for optimal performance.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1197 family of 10-bit ADCs, which also includes variants like the LTC1197CMS8 and LTC1197IMS8. These devices share core architectural features but differ in packaging options such as SOIC and MSOP, and operating temperature ranges. The 'L' designation typically indicates extended low-voltage operation capabilities.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include other members of the LTC1197 family such as the LTC1197CMS8#PBF or LTC1197IMS8#PBF, provided the package type matches the PCB footprint. For higher resolution needs, consider the LTC1199 series.
