The wd7745 voltage reference and ad7745 on-chip clock generator eliminate the need for any external components in capacitive sensor applications.

Model The model number is a specific ad7745 of a generic that can be purchased or sampled. You can change your cookie settings at ad7745 time. Most orders ship within 48 hours ad7745 this date. Evaluation Ad7745 Pricing displayed is based on 1-piece. The resistors used were ad7745 and had the following values: It is recommended to setup the CapDAC to have the intended calibration point of the application at zero-scale of the capacitive input range.
