LTC1199LCMS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1199LCMS8#TRPBF is a 10-bit successive approximation analog-to-digital converter (ADC) in an 8-lead MSOP package. It features a software-selectable 2-channel multiplexer and operates on a single 2.7V to 4V supply. The device achieves a maximum sampling rate of 250ksps with typical power dissipation of 2.2mW at full speed. It utilizes an auto-shutdown feature that reduces supply current linearly as the sample rate decreases, drawing only leakage current during idle periods. The internal reference is tied to VCC.

Analog To Digital Converters (ADC) Feature Summary

• 10-Bit Resolution with 250ksps Maximum Sampling Rate
• Software-Selectable 2-Channel Multiplexer
• Single 2.7V Supply Operation with Auto Shutdown
• 3-Wire SPI/Microwire Compatible Serial Interface

Analog To Digital Converters (ADC) Applications

• Portable or Compact Instrumentation
• Low Power or Battery-Operated Instrumentation
• High Speed Data Acquisition Systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'L' suffix indicates the 2.7V–4V operating range variant. Confirm the 'MS8' designation corresponds to the 8-lead MSOP package. Ensure the '#TRPBF' suffix matches the required tape-and-reel packaging format for surface mount assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the standard LTC1199 if operation below 4V is required. The LTC1199L series supports a minimum supply voltage of 2.7V, whereas the non-L version requires a minimum of 4V. Verify that the 250ksps maximum sampling rate at 2.7V meets system timing requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1197/LTC1199 family of 10-bit switched-capacitor ADCs. The LTC1199 variant specifically includes a 2-channel input multiplexer, distinguishing it from the differential-input-only LTC1197. The 'L' suffix denotes the low-voltage version optimized for 2.7V systems.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1197L serves as a pin-compatible alternative but lacks the multiplexer. The LTC1196/1198 are 8-bit predecessors. Verify interface compatibility when substituting with other SAR ADCs.
