LTC1199CMS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1199CMS8#PBF is a 10-bit successive approximation register (SAR) analog-to-digital converter in an 8-lead MSOP package. It features a software-selectable 2-channel multiplexer and operates on a single 4V to 6V supply. The device supports sampling rates up to 450ksps with a typical power dissipation of 25mW at full speed. It utilizes a 3-wire serial interface compatible with SPI and Microwire protocols, includes auto-shutdown capabilities for reduced power consumption at lower sample rates, and accepts differential or single-ended inputs.

Analog To Digital Converters (ADC) Feature Summary

• 10-bit resolution with 450ksps maximum sampling rate
• Software-selectable 2-channel input multiplexer
• Single 4V to 6V supply operation with 25mW typical power dissipation
• Auto-shutdown mode reduces power linearly 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 #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the 'C' temperature grade corresponds to the required operating range of 0°C to 70°C. Ensure the 4V to 6V supply voltage requirement aligns with the system design constraints.

Analog To Digital Converters (ADC) Selection Notes

Select this component over the LTC1197 series if a built-in 2-channel multiplexer is required, as the LTC1197 lacks this feature. Verify that the 4V minimum supply voltage meets the system's power budget, as the LTC1199L variant supports lower 2.7V operation. Ensure the serial interface timing matches the host microcontroller's SPI or Microwire configuration.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1199 family of 10-bit SAR ADCs. It shares architectural similarities with the LTC1197 but differs by integrating a 2-channel MUX and having a fixed internal reference tied to VCC. It serves as a 10-bit upgrade path for older 8-bit devices like the LTC1196 and LTC1198.
