The AD has one capacitance ad7745 channel, while the AD has two channels. Applications Automotive, Industrial and Medical Systems for: An AD demo board with a range extension circuit was used to perform the measurements.

Calculating the gain calibration factor value ad7745 out: It is recommended to setup the CapDAC to have the intended calibration point of the application at ad7745 of the capacitive input range.

At ad7745 one model within this product family ad7745 in production and available for purchase. For each measurement taken, the capacitance was set to the desired value using the LCR meter, then connected ad7745 the range extension board measuring the capacitance seen by the AD Community Discussion In Engineering Zone.

Product Ad7745 Production At least one model within this product family is in production and available for purchase.

Pin Count is ad7745 number of pins, ad7745, or pads on the device. Sensors with higher capacative ad7745. Didn’t find what you were looking for? For volume-specific price or delivery quotes, please contact your local Analog Devices, Inc. Each channel can be configured as single-ended or differential. This can be one of 4 stages: Select the purchase ad7745 to display inventory availability ad7745 online purchase ad7745.

The various ranges specified are as follows:. All ad7745 measurements show similar behavior and are linear; therefore, the error caused by the range extension circuit can be easily compensated for in software. The Purchase button will be displayed if model is available for purchase online at Analog Devices or one of our authorized distributors.

Reading AD with Arduino Mega

Please be aware that parts of this ad7745, such as myAnalog, will not function correctly if you disable ad7745. An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board.

ADI has always placed the highest emphasis on delivering products ad7745 meet the maximum levels of quality and reliability. Ad7745 technical data of such a capacitive sensor element are shown in Table 1. Please Select a Region. Pricing displayed is based on 1-piece.
