INTRODUCTION
The EVAL-PRAOPAMP-4R/4RU is an evaluation board which accommodates quad op amps in SOIC and TSSOP packages. It is meant to provide the user with multiple choices and extensive flexibility for different applications circuits and configurations.
This board is not intended to be used with high frequency components or high speed amplifiers. However, it provides the user with many combinations for various circuit types including active filters, instrumentation amplifiers, composite amplifier, and external frequency compensation circuits. For examples of application circuits refer to ADI amplifier data sheets under the applications section. This application note will present different implementations of filter design using quad amplifiers.
