vdd vcc vss vpp represents a topic that has garnered significant attention and interest. What is the difference between \$V_ {CC}\$, \$V_ {DD}\$, \$V_ {EE .... Why VDD and not simply VD? The convention of letters V AB for voltage means the potential between A and B. Voltage is a potential measured with respect to another point in the circuit. Another key aspect involves, what is Vcc, Vss, Vdd & Vee? In relation to this, - All About Circuits.
Vcc = Collector supply voltage, Vee = Emitter supply, Vdd = Drain supply, Vss = source supply. The voltages can be negative or positive depending on the the device and the circuit configuration. Moreover, what is PVDD and AVDD? Moreover, - Electrical Engineering Stack Exchange. This perspective suggests that, i know VDD,VCC,VEE and VSS and what they stand for.
But when I came across this circuit: I saw this. Those PVDD and AVDD terms? What to do they convey or stand for? This circuit is amplifier circu...

A difference between Vdd and Vddio in datasheet of a sensor. I guess, VDD would be a supply voltage for the sensor's core logic, whereas VDDIO is the voltage that IO can accept. To make it voltage universal, for example, the VDD can be 3.3V and the IO pins can support 2.8V, 3.3V or 5V input levels without the need of level shifters. What are VDDA and VSSA?
In your case, VSSA means "lower voltage analog supply rail", and it's mated with VDDA, which is the voltage analog supply rail. Furthermore, so VSSD would be the digital VSS, VDDD would be the digital VDD (and I've never seen VDDD, but strange things are out there). It's certainly conceivable that you'll see VDD1, VDD2, etc., on a multi-supply board or chip. What is Vdd, VD, Vs, and Vss?

So Vdd is the supply voltage associated with the drain node of an NFET circuit and Vss is the supply voltage associated with the source node of an NFET circuit. Not everything follows this convention and you need to learn to interpret things in terms of the schematic you are working with. Vs, in particular, is a common notation for a signal source. What is VDD in this context?
On this page, the two versions of this gyro/accelerometer IC have two different Logic Supply Voltages. What is the VDD voltage? Why would one version of the chip also have an option to make the v...
