Questions about the ADC Resolution poster

What’s on the ADC Resolution poster?

The rule, 3 worked examples, and the mistake everyone makes. An ADC's step size is its reference voltage divided by the number of available codes.; LSB = V_ref / 2ⁿ · codes = 2ⁿ; 12-bit, 3.3 V ref = 0.81 mV per step; 10-bit, 5 V ref = 4.9 mV per step; True accuracy = Set by the reference; Common mistake: Reading extra bits as extra accuracy → Accuracy comes from reference…. Give the sample-and-hold capacitor time to charge: a high source impedance needs a longer sampling window, or a buffer.

Who is the ADC Resolution poster for?

ADC Resolution belongs to the Electrical Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning embedded systems can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the ADC Resolution poster?

Use it to size a converter, and to work out which of its bits mean anything. A wall chart earns its place by being glanceable from where the work is happening, so ADC Resolution belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.

What other posters go with ADC Resolution?

Driving Loads, GPIO & Pull Resistors and Writing an ISR sit alongside ADC Resolution in the Electrical Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Driving LoadsGPIO & Pull ResistorsWriting an ISR

Is the ADC Resolution poster free to download and print?

Yes. ADC Resolution downloads as a free PDF with no account, no email and no watermark, like everything else in the Electrical Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence

What size does the ADC Resolution poster print at?

ADC Resolution is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of ADC Resolution loses nothing.Printing guide
