    Chapter 1 Introduction This user’s guide describes the universal operational amplifier single, dual, quad (SOIC) evaluation module (EVM) with shutdown (SLOP248). The EVM simplifies evaluation of Texas Instruments surface-mount op amps with or without shutdown feature. Topic Page Design Features .
  • Page 8: Design Features

    Design Features 1.1 Design Features The EVM board design allows many circuits to be constructed easily and quickly. There are three circuit development areas on the board, and each uses IC amplifiers in the SOIC package. Area 100 is for a single operational amplifier (op amp), with or without shutdown.
