The voltage level by which an electrical system is designated and to which certain operating characteristics of the system are related.

5V

Polarity

Inverting

Power Supplies

an electronic circuit that converts the voltage of an alternating current (AC) into a direct current (DC) voltage.?

5V

Load Capacitance

the amount of capacitance measured or computed across the crystal terminals on the PCB. Frequency Tolerance. Frequency tolerance refers to the allowable deviation from nominal, in parts per million (PPM), at a specific temperature, usually +25°C.

Propagation Delay

the flight time of packets over the transmission link and is limited by the speed of light.

32 ns

Quiescent Current

The quiescent current is defined as the current level in the amplifier when it is producing an output of zero.

4μA

Turn On Delay Time

Turn-on delay, td(on), is the time taken to charge the input capacitance of the device before drain current conduction can start.

Output Function

An output function is a function that an optimization function calls at each iteration of its algorithm. Typically, you use an output function to generate graphical output, record the history of the data the algorithm generates, or halt the algorithm based on the data at the current iteration.
