How to level shift from 0 to 5 volts?
To level shift a 0 to 10 volt source to 0 to 5 volts, the circuit below will provide this: Any pair of equal resistor values can be used. Typically 10K to 100K. The higher the resistance pair, the less of a load you will impose on the circuit.
Which is an example of a level shifting circuit?
Since this is a linear analog amplifier, any voltage, positive or negative will be exactly one half on the output. Another example is a piece of equipment that provides a signal from 0 to +.1 volts and the remote metering circuit is looking for a 0 to +10 volt signal.
What should be the voltage divider on a VIN?
If we have -2.5 V on the Vin input the non-inverting input should be zero if you want 0 V out, regardless of the values of R3 and R4. So R1 and R2 form a voltage divider, and R2 should be twice R1 to get the 0 V.
How to calculate the voltage of a voltage divider?
The circuit above shows a voltage divider circuit involving a 2kΩ and a 1kΩ resistor. If the voltage from the microcontroller is 5V, then the leveled-down voltage to the sensor is calculated as: V out = 5 ∗ 2kΩ 2kΩ +1kΩ = 3.33V V o u t = 5 ∗ 2 k Ω 2 k Ω + 1 k Ω = 3.33 V
Why do I need a precision voltage reference?
Other possible reasons include using one to calibrate your DMM, or to construct a precision voltage-to-frequency converter or current source. The applications for a precision reference fall into two general categories: instrument (DMM, DVM) calibration/accuracy verification, or as a circuit component, such as the reference for an A/D converter.
How to build a.01% accurate voltage reference?
The X60008C is used in the construction part of this article and costs about $7.50, provides 5.000V accurate to within 500 µV (.01%) , has a low temperature coefficient of 5 ppm/°C, low aging rate of 10 ppm/1,000 hours, and incredibly low supply current requirement of 800 nA. Figure 5 shows a schematic using this device.
What should I look for in a level shifter?
What Does a Level Shifter Do? A level shifter translates logic signals from one level to another. Usually, this shift takes place between 5V and 3.3V, but you can use other voltages as needed, such as 2.5V or 1.8V. Important specs to look for include:
How does a level shift work on a logic chip?
This shifter can convert logic levels from inputs up to 5.5V down to between 3.6V and 1.65V, depending on the Voltage (VCC) powering the device. The direction-control (DIR) pin selects the shift’s direction from one or more of the eight A or B input or output pins to its counterpart on the other side of the chip.
