1 Overview

This document contains information for the ADS117L11 (WQFN package), ADS127L11 (TSSOP and WQFN packages), ADS127L21 (WQFN package), and ADS127L21B (WQFN package) to aid in a functional safety system design. Information provided are:

  • Functional safety failure in time (FIT) rates of the semiconductor component estimated by the application of industry reliability standards
  • Component failure modes and their distribution (FMD) based on the primary function of the device
  • Pin failure mode analysis (pin FMA)

Figure 1-1 shows the device functional block diagram for reference.
