LTC1197LCMS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1197LCMS8#TRPBF is a 10-bit successive approximation register (SAR) analog-to-digital converter in an 8-lead MSOP package. It operates on a single 2.7V to 4V supply with a maximum sampling rate of 250ksps. The device features a differential analog input and an external reference pin, supporting unipolar operation. Power dissipation is typically 2.2mW at full speed, utilizing auto shutdown to reduce current linearly at lower sample rates. It employs a 3-wire serial interface compatible with SPI and Microwire protocols.

Analog To Digital Converters (ADC) Feature Summary

• 10-bit resolution with 250ksps maximum sampling frequency
• Differential analog input with adjustable external reference
• Single 2.7V to 4V supply operation with 2.2mW typical power dissipation
• Auto shutdown functionality reduces power consumption at lower sample rates

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems
• Portable or compact instrumentation
• Battery-operated instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the LC suffix corresponds to the commercial temperature range of 0°C to 70°C as defined in the manufacturer's documentation. Ensure compatibility with the required voltage levels for the digital interface relative to the 2.7V to 4V operating supply.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring a 10-bit SAR ADC with low power consumption under a 2.7V supply. The differential input architecture allows measurement of signals floating on a DC common mode voltage. Consider the 250ksps limit when designing for higher throughput requirements, as the non-L version supports up to 500ksps at 5V.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1197/LTC1197L family of 10-bit ADCs. It shares architectural similarities with the LTC1199 series but differs in having a differential input and external reference rather than a multiplexer. The MSOP package provides a compact footprint suitable for space-constrained designs compared to larger SO packages.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1197CMS8#PBF serves as a pin-compatible alternative within the same family, differing primarily in the standard 5V supply specification instead of the 2.7V L-version capability.
