Didn’t find what you were looking for? Each part contains a fixed resistor with a wiper contact that taps the fixed resistor value at a point determined by a digital code loaded into the controlling serial input register. I only need the digital pot to work then I am coasting! Make sure you are wiring it up correctly and you have changed the pin numbers to suite the new chip.

This is the date Analog Devices, Inc. View Detailed Evaluation Kit Information. The AD contains a single variable resistor in the compact SO-8 package.

Can we get 4 different frequencies analog outputs simultaneously from AD IC.

I have very little experience with ICs. Model Package Pins Temp. Temperature Range This is the acceptable operating range of the device. Pricing displayed for Evaluation Boards and Kits is based on 1-piece pricing.

A serial data output pin at the opposite end of the serial register allows simple daisy-chaining in multiple VR applications without additional external decoding logic.


Pin Count Pin Count is the number of pins, balls, or pads on the device.

Please be aware that parts of this site, such as myAnalog, will not function correctly if you disable cookies. An Evaluation Board is a board engineered to show the performance of the model, the part is included on the xd8402.

I assume this is built in. Hi Mike Thanks for your input. Please consult the datasheet for more information. I’m not capable of changing the transmission mask. Most orders ship within 48 hours of this date.

Indicates the ad8420 option of the model Tube, Reel, Tray, etc. Digital Potentiometers – Where and How to Use. I will post the schematic once I find out how!

Jared – AD8402

Understanding and Applying Digital Potentiometers. It is important to note the scheduled dock date on the order entry screen. I am using duemilanove and AD which has 4 pots. Ad84402 a model is not available for web samples, look for notes on the product page that indicate how to request samples or Contact ADI.

We achieve ad84402 by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. The various ranges specified are as follows:. That is the code I looked at in the tutorial, as I said I can’t see much wrong with it.


SPID digital pot using AD

The SPI library is not built in it has to be ‘included’ in your sketch. The package for this IC i. For volume-specific price or delivery quotes, please contact your local Analog Devices, Inc. Although in the Arduino Mega it says the following: The AD contains av8402 independent variable resistors in saving SO surface mount package.

Access Denied

I have already sorted a liquid crystal display and a controller. The various ranges specified are as follows: Each variable resistor offers a completely programmable value of resistance, between the A terminal and the wiper or the B terminal and the wiper. Pin Count is the number of pins, balls, or pads on the device.

These VR latches are updated from an SPI compatible serial-to-parallel shift register that is ar8402 from a standard 3-wire serial-input digital interface.

This is the complete code: I tried using a Duemilanove and it ad842 perfectly. Evaluation Boards Pricing displayed is based on 1-piece. On closer inspection i found the AD takes an 11 bit instruction and the AD takes a 10 bit.
