A serial data output pin at the opposite end ad802 the serial register allows simple daisy-chaining in multiple VR applications without additional external decoding logic. International prices may vary due to local duties, taxes, fees and exchange rates. The various ranges specified are as follows: Ten data bits make up the data word clocked into the serial input register.

I only need the digital pot to work then I am coasting! The AD supports a single-supply 2.

Jared – AD8402

I have already sorted a liquid crystal display and a controller. A unique switching circuit minimizes the high ac8402 inherent in traditional switched resistor designs avoiding any make-before-break or break-before-make operation.

I understand that you only need one bit for 2 pots but the data sheet didn’t differentiate between two or four pots.


I had to define these pins in aad8402 sketch. Most orders ship within 48 hours of this date. The package for this IC i. On closer inspection i found the AD takes an 11 bit instruction and the AD takes a 10 bit.

Can you post a schematic of what you actually built?

I will try and continue this tomorrow. The AD has eight pots so it needs three bits to address 0 to 7. First off, hit the modify button and highlight the code and click on the icon. The Purchase button will be displayed if model is available for purchase online at Analog Devices or one of our authorized distributors. That is the code I looked at in the tutorial, as I said I can’t see much wrong with it. Model Package Pins Temp. The Sample button will be displayed if a model is available for web samples.

The SPI library is not built in it has to be ‘included’ in your sketch. Pin Count is the number of pins, aad8402, or pads on the device.

Due to environmental concerns, ADI offers many of our products in lead-free versions.

Can you post a link to the tutorial you are following. Hi Grumpy mike The tutorial is at http: Make sure you haven’t left out any of the pins, even the ones you are not using need to be tied high or low depending on what you want them to be. Select the purchase button to display inventory availability and online purchase options. 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’m sure it’s not too difficult but i just can’t ad88402 it. Indicates the packing option of the model Tube, Reel, Tray, etc.

Please Select a Language. Pricing displayed for Evaluation Boards and Kits is based on 1-piece pricing. For volume-specific price or delivery quotes, please contact your local Analog Devices, Inc.

This is the date Analog Devices, Inc. Have to go now. Temperature ranges may vary by model. An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board. International prices may ad402 due to local duties, taxes, fees and exchange rates.

However, if it compiles without errors then it must know about it. Product Lifecycle Production At least one model within this product family is in production and ad840 for purchase. I can’t see the line that does that.

This is the complete code: The specific part is obsolete and no longer available. Please be aware that parts ad802 this site, such as myAnalog, will not function correctly if you disable cookies.
