High voltage digital potentiometer

Free Intuitive Toolkit Software Allows Configuration, Calibration and Logging. The analog power rail allows high voltage on the. It features 8-bit resolution. Is digital potentiometer a real replacement for mechanical potentiometer or are there restrictions regarding voltage potentials?

If I use the digital potentiometer in audio volume control, will I experience zipper noise?

This device can be used as a programmable resistor or resistor divider. Digital potentiometers from Maxim include a wide selection of volatile and nonvolatile digipots in linear and log taper, and programmable precision voltage dividers. Programming is accomplished by an I²C-compatible.

Figure A: There is always one more tap than the number of resistance values in a digital potentiometer. In this case, 1taps and 1resistors. Microchip Technology announced the expansion of its V digital potentiometer (digipot) portfolio with the addition of two (2) volatile I2C devices, the MCP45HV31.

Does anyone know if it exist high current digital potentiometer you can control with arduino?

Those I find usually use the same current and voltage for input and output. I am currently looking for something that would withstand 10A. A Digital potentiometer also known as digipot, is similar to a standard analogue potentiometer , which is a variable resistor except the digital potentiometer has an integrated chip (IC) that accepts a signal input rather than the physical movement of a shaft. Schmitt Trigger High -Level Input Voltage V IH 0. VDD — Low-Level Output Voltage V. Although replacing an analog pot with a digital potentiometer may seem like a simple drop-in, limitations on voltage headroom and adjustment resolution can appear to eliminate them from contention. This means it has six variable resistors ( potentiometers ) built in for individual electronic control.

About of these are switching power supply, are sensors, and are integrated circuits. Purpose is to reduce the supply voltage. If you can get away with a limited number of values an providing there is always a net positive voltage on one wire with respect to the other, you could use a. Mouser is an authorized distributor for many digital potentiometer. About of these are switching power supply, are sensors, and are relays.

High - Voltage Tolerant Digital Inputs: Up to 12. V - Device Characteristics Specified - 1. Carefully selected high -quality materials, paired with decades of experience in the development and production of linear and rotary sensors, are the guarantee for a long service life without any function loss. The idea I had is to use a digital potentiometer to control a variable voltage regulator.

Control the amplifier Gain and. The higher the input voltage , the larger the digital value. Potentiometers Many application such like : 1)volume controls on audio equipment. The Hi-V Digipot module can be used in place of standard mechanical potentiometer as long as the voltage and current limits are not exceeded.

The minimum input voltage is 4. It is a 7bit digital potentiometer featuring an output voltage range of 15. For some of our prototypes we are looking for high resistance digital potentiometers. We need to replace several analog 1-Mohm rotary potentiometers at 9-18V with. I guess no digital potentiometer will allow you to do what you want.

They are tipically used to drive low- voltage electronic circuits. You probably need an adjustable transformer (varivolt) or some kind of switching AC-AC converter to achieve what you want. Yes - that should be possible, provided your digital pot has the same ohm range as the physical pot.
