LTC1197CMS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1197CMS8#PBF is a 10-bit successive approximation register (SAR) analog-to-digital converter in an 8-lead MSOP package. It features a single differential analog input and an external reference pin. The device operates on a single 4V to 9V supply with a maximum sampling rate of 500ksps at 25°C. Typical power dissipation is 25mW at full speed. It utilizes a 3-wire serial interface compatible with SPI and Microwire protocols. The component supports auto-shutdown to reduce power consumption linearly as the sample rate decreases.

Analog To Digital Converters (ADC) Feature Summary

• 10-bit resolution with up to 500ksps sampling rate
• Single-ended or differential analog input configuration
• External voltage reference input for ratiometric applications
• Auto-shutdown mode reduces supply current at lower sample rates

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems
• Portable or compact instrumentation
• Low power or battery-operated instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix CMS8 corresponds to the commercial temperature range (0°C to 70°C) and MSOP package variant. Confirm RoHS compliance status through official manufacturer documentation prior to procurement, as environmental certifications may vary by production batch.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring a differential input and external reference control within a compact MSOP footprint. Ensure the system supply voltage remains between 4V and 9V. For lower voltage operation down to 2.7V, consider the LTC1197L series instead. Verify that the host microcontroller supports the required 3-wire synchronous serial interface timing.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1197 family of 10-bit SAR ADCs. It shares architectural similarities with the LTC1199, which includes a multiplexer, but lacks the internal MUX and DIN pin found in the LTC1199 variants. It serves as a high-speed upgrade to older 8-bit devices like the LTC1196 and LTC1198.
