This user's guide describes the characteristics, operation, and use of the OPA862DEVM. This evaluation
module (EVM) is an evaluation and development kit for evaluating the OPA862ID, a single-ended-to-
differential amplifier that interfaces single-ended sources to fully-differential amplifiers (FDAs) or
differential-input, analog-to-digital converters (ADCs). A complete circuit description as well as schematic
diagram and bill of materials are included in this document.
Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with
the OPA862DEVM.
