LTC1199LCS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1199LCS8#TRPBF is a 10-bit successive approximation analog-to-digital converter (ADC) 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 software-selectable 2-channel multiplexer and a 3-wire serial interface compatible with SPI and Microwire protocols. Power dissipation is typically 2.2mW at full speed, utilizing automatic shutdown to reduce current linearly as the sample rate decreases.

Analog To Digital Converters (ADC) Feature Summary

• 10-bit resolution with 250ksps sampling rate at 2.7V
• Software-selectable 2-channel input multiplexer
• Single 2.7V to 4V supply operation
• Automatic power down reduces supply current 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 TRPBF indicates tape and reel packaging when sourcing. Confirm that the L variant strictly adheres to the 2.7V to 4V operating range and does not support higher voltage supplies required by non-L versions.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring a 2-channel MUX and low-voltage operation. Ensure the system clock frequency does not exceed 3.5MHz at 2.7V to maintain accuracy. Verify digital logic levels meet TTL thresholds relative to the VCC supply.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1197/LTC1199 family of micropower ADCs. The LTC1199 variant specifically includes a built-in 2-channel multiplexer, distinguishing it from the differential-input-only LTC1197. The 'L' designation specifies the low-voltage 2.7V capability.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1197LCS8#TRPBF is a pin-compatible alternative but lacks the internal multiplexer and requires an external reference. Higher voltage variants like the LTC1199CS8#TRPBF require 4V to 6V supplies.
