How are digital potentiometers used in Analog Devices?
Analog Devices portfolio of digital potentiometers are specified with varying tolerances of 20% down to 1% to match the most stringent precision and accuracy needs. Some digital potentiometers, such as the AD5258 / AD5259, factory test the error tolerance and store the results in user accessible memory to allow resistor matching at production.
What is the ds1882 dual log digital potentiometer?
The DS1882 is a dual, nonvolatile (NV) digital potentiometer designed to operate in audio systems that accomodate up to ±7V signal levels. The potentiometer settings can be stored in EEPROM so that they are retained when the power is cycled. The DS1882 has separate supplies for the potentiometers (V CC) and the communication circuitry (V DD ).
When to use an OTP or digital potentiometer?
The wide variety of memory options allow the digital potentiometer choice to be tailored to the particular system. For example, for systems that require constant adjustment volatile digital potentiometers can be used. For systems that only require a calibration on factory testing, an OTP potentiometer can be used.
What makes a digital potentiometer resilient to shocks?
A digital potentiometer consists of a number of CMOS transmission gates (see Figure 1). As there are no mechanical elements, the digital potentiometer is resilient against shocks, wear, aging, and contact. Figure 1.
Analog Devices portfolio of digital potentiometers provide uncompromising performance across a wide range of industrial temperatures. Sometimes called digital pots, RDACs, or digiPOTs, these compact devices can be used to calibrate system tolerances or dynamically control system parameters.
What can a digipot analog device be used for?
Digital Potentiometers (DigiPOT) Analog Devices portfolio of digital potentiometers provide uncompromising performance across a wide range of industrial temperatures. Sometimes called digital pots, RDACs, or digiPOTs, these compact devices can be used to calibrate system tolerances or dynamically control system parameters.
Is there a way to change the resistance of a digital potentiometer?
A similar article appeared in the March 20, 2008 edition of EDN magazine. This application note describes a simple method that uses an external analog voltage to change the resistance of a digital potentiometer.
Is the mcp41010 a single channel digital potentiometer?
The MCP41010 is a single-channel, 256-position digital potentiometer available in an 8-pin PDIP or SOIC package. Now to the pin description of MCP41010:
What is the product resistance of a digital potentiometer?
Digital Potentiometers Product Resistance (kΩ) MCP4011 2.1, 5, 10, 50 MCP4012 2.1, 5, 10, 50 MCP4013 10,2.1,5,50 MCP4014 2.1, 5, 10, 50
