LTC1199IS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1199IS8#TRPBF is a 10-bit successive approximation register (SAR) analog-to-digital converter in an 8-lead SOIC 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. Key electrical characteristics include a signal-to-noise plus distortion ratio of 60dB, 1LSB DNL, and a gain error of 4LSB.

Analog To Digital Converters (ADC) Feature Summary

• 10-Bit Resolution with 450ksps Sampling Rate
• Software-Selectable 2-Channel Input Multiplexer
• Single 4V to 6V Supply Operation
• Auto Shutdown for Low Power Consumption

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 ordering suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the IS8 designation corresponds to the industrial temperature range (-45°C to +85°C) and the SOIC-8 package style required for the design.

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. Ensure the application voltage does not exceed 6V, as the LTC1199 is limited to a maximum of 6V compared to the LTC1197's 9V limit.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1197/LTC1199 family of 10-bit SAR ADCs. While sharing similar architecture and performance metrics, the LTC1199 variant is distinguished by its integrated multiplexer and a stricter maximum supply voltage rating of 6V.
