AD with a kΩ fixed resistance per potentiometer. Features. The AD series of digital potentiometers provides these features: • position variable. I’ve followed the Tutorial for the SPID digital pot using the AD but I want to use the AD Mostly things looked good until I tried to run. Analog Devices Inc.

I had the same problem. The package for this IC i. What results are you seeing? Most orders ship within 48 hours of this date. An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board.
Jared – AD8402
The model has not been released to general production, but samples may be available. The product is appropriate for new designs but newer alternatives may exist. Perhaps it is something to do with the SPI library? That way sd8402 is formatted correctly. The AD supports a single-supply 2. You can change your cookie settings at any time.
The resistance between the wiper and either endpoint of the fixed resistor varies linearly with respect to the digital code transferred into the VR latch. International prices may vary due to local duties, taxes, fees and exchange rates.
This is the acceptable operating range of the device. Please Select a Language. Transit times from these sites may vary. This is the date Analog Devices, Inc. Frequently Asked Questions 1. The data word is decoded where the first two bits determine the address of the VR latch to be loaded, the last eight bits are data. View Detailed Evaluation Kit Information. Although in the Arduino Mega it says the following: I will try and continue this tomorrow.
Due to environmental concerns, ADI offers many of our products in lead-free versions. Hi Grumpy mike The tutorial is at http: These devices perform the same electronic adjustment function as a potentiometer or variable resistor. I’m not capable of changing the transmission mask.
Can we get 4 different frequencies analog outputs simultaneously from AD IC. Each VR has its own VR latch that holds its programmed resistance value. Please consult the datasheet for more information.
I have already sorted a liquid crystal display and a controller. The AD contains a single variable resistor in the compact SO-8 package.
For volume-specific price or delivery quotes, please contact your local Analog Devices, Inc. How are you measuring the outputs? Please be aware that parts of this site, such as myAnalog, will not function correctly if you disable cookies. Pin Count Pin Count is the number of pins, balls, or pads on the device. Pricing displayed for Evaluation Boards and Kits is based on 1-piece pricing.
It is important to note the scheduled dock date on the order entry screen. Didn’t find what you were looking for? Understanding and Applying Digital Potentiometers. However, if it compiles zd8402 errors then it must know about it. Hi Mike The AD has only two pots so the address is 2 bits.
SPID digital pot using AD
Can you post a schematic of what you actually built? Comparable Parts Click to see all in Parametric Qd8402. Status Status indicates the current lifecycle of the product.
The Purchase button ad802 be displayed if model is available for purchase online at Analog Devices or one of our authorized distributors. These VR latches are updated from an SPI compatible serial-to-parallel shift register that is loaded from a standard 3-wire serial-input digital interface.
International prices may differ due to local duties, taxes, fees and exchange rates. I have very little experience with ICs.
