MCP651 Input Offset Evaluation Board (MCP651EV-VOS)

The MCP651 Input Offset Evaluation Board is intended to provide a simple means to measure the MCP651 Input Offset Evaluation Board op amp’s 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.

Возможности

    • Test Points for inputs (bias the DUT at any desired point), outputs (to measure VOS and the DUT's supply current) and others (power supplies, setting the MCP651's VCAL voltage, etc.)
    • Potentiometer to set MCP651's VCAL voltage
    • Push button switch to initiate a calibration sequence in the MCP651
    • DIP switch to select either high or low gain for the measured offset (VOS)
    • DUT footprints for either SOIC-8 or PDIP-8 parts
