http://www.microchip.com/MCP651 This video gives a brief overview of the MCP651 evaluation board. The new family of MCP65x operational amplifiers with mCal technology and many of the features of the evaluation board are discussed throughout this video. The MCP651 Input Offset Evaluation Board is intended to provide a simple means to measure the MCP651 Input Offset Evaluation Board op amps input offset voltage under a variety of operating conditions. The measured input offset voltage (VOST) includes the input offset voltage specified in the data sheet (VOS) plus changes due to: power supply voltage (PSRR), common mode voltage (CMRR), output voltage (AOL), input offset voltage drift over temperature (ΔVOS/ΔTA) and 1/f noise. The MCP651 Input Offset Evaluation Board works most effectively at room temperature (near +25°C). Measurements at other temperatures should be done in an oven where the air velocity is minimal.
