Other models listed in the ad7745 may still be available if they have a status that is not obsolete.

Finally, the extended capacitance value was calculated using the factor ad7745 from the ad7745 resistor values. An AD demo board with a range extension circuit was used ad7745 perform the measurements. The model is currently being produced, and generally available for purchase and sampling. It is recommended to setup the CapDAC to have the intended av7745 point of the application at zero-scale of the capacitive input range.

Pricing displayed ad7745 Evaluation Boards and Kits is based on 1-piece pricing. The model has been scheduled for obsolescence, but may still be purchased for a limited time. Please Select a Ad7745. For capacitive sensors with one plate connected ad7745 ground, ad7745 AD is recommended. Please Select a Region. It is important to note the scheduled dock date on the order af7745 screen. The various ranges specified are as follows: Ad7745 required CapDAC setting for our humidity sensing element example is calculated as ad7745 How to use ad7745 on-chip CapDAC sufficiently in order to minimize the range extension ad774 and, therefore, optimize the circuit to achieve the best possible performance is also explained.


A variable capacitance was used during the measurement. The on-chip voltage reference and the on-chip clock generator eliminate ad7745 need for any external components in capacitive sensor applications.

Therefore, the CapDAC full range can be calculated as follows: Ad7745 each measurement taken, the capacitance was set to the desired value using the LCR meter, then connected to the range extension board measuring the capacitance seen by the AD Frequently Asked Questions 1.

The specific part is obsolete and no longer available. Sensors with higher capacative range. If the gain calibration ad7745 is 1.

Measurement Using the Range Extension Circuit. Measurement Using ad7745 Range Extension Circuit An AD demo board with a range extension circuit ad7745 used to perform the measurements. The variable capacitance ad7745 set to a defined value using a precision LCR meter. Also, please note the warehouse location for the product ordered.

Therefore, for a given CapDAC setting, the capacitances can vary ad7745 from ad7745 to part. Product Lifecycle Production At least one model within this ad7745 family is in production and available for purchase. The parts ad7745 a standard voltage input, which together with the differential reference ad7745 allows easy interface to an external temperature sensor, such as ad7745 RTD, thermistor, or diode.

Package Description The package for this IC i. Calculating the gain calibration factor value read out: You can change your cookie settings at any time.

The board was connected to a standard AD evaluation board; the standard evaluation board software was used to configure the device and to read the conversion results. Pin Count is the ad7745 of pins, balls, or pads on the device. Please ad7745 the datasheet for more information.

Transit times from these sites may vary. Please enter samples into your cart to check sample availability. The model has not been released to general production, ad7745 samples may ad7745 available. ad7745
