Working Principle

The 4116R-1-250 works by using a combination of a DAC and a resistor array. The DAC’s job is to accurately convert the binary data into a desired analog voltage level, while the resistor array divides the output voltage into several segments. The output of the resistor array is then fed into a buffer amplifier which increases the stability and limits noise.

The output of the buffer amplifier is then fed into a multiplexer whose job it is to select the correct output based on the binary data. The multiplexer’s output is then fed into the final output buffer amplifier which ensures the voltage stays within the desired range and prevents any noise from occurring.

The 4116R-1-250 also features footer detection, temperature sensing, latch sensing, and power monitoring capabilities. Footer detection allows the circuit to detect whether a user is using an ill-suited output voltage and will act accordingly. Temperature sensing allows the circuit to make any necessary adjustments when the temperature fluctuates. Latcher sensing prevents any current from flowing when an output is not in use, and power monitoring ensures the circuit does not draw more current than it is designed to.

In conclusion, the 4116R-1-250 is a precision resistor network that is designed to accurately convert binary data into a desired analog voltage with maximum accuracy. It is designed for use in high accuracy control applications and uses a combination of a DAC and a resistor array to do its job. It also offers additional features such as footer detection, temperature sensing, latch sensing, and power monitoring.
