 | Kit Overview
The Analog Devices EVAL-AD5110SDZEVAL-AD5110SDZ evaluation board for evaluating the AD5110AD5110 a single-channel, 128-position, nonvolatile memory digital potentiometer. The AD5110 supports single-supply 2.3 V to 5.5 V operation, making the device suited for battery-powered applications and many other applications, offering guaranteed low resistor tolerance errors of ±8% and high bandwidth while allowing up to ±6 mA current density in the A, B, and W pins.
The logic voltage levels operate from single 1.8 V to 5.5 V supplies. The versatile I2C-compatible digital interface allows readback of the wiper register and EEPROM content which contain the resistor tolerance, providing an end-to-end tolerance accuracy of 0.1%. The EVAL-AD5110SDZEVAL-AD5110SDZ can operate in single-supply mode and incorporates an internal power supply from the USB.
The AD5110AD5110 provides a nonvolatile solution for 128-position adjustment applications, offering guaranteed low resistor tolerance errors of ±8% and up to ±6 mA current density in the A, B, and W pins. The new low wiper resistance feature minimizes the wiper resistance in the extremes of the resistor array to only 45 Ω, typical. The wiper settings are controllable through an I2C-compatible digital interface that is also used to readback the wiper register and EEPROM content. Resistor tolerance is stored within EEPROM, providing an end-to-end tolerance accuracy of 0.1%.
This evaluation board requires an SDP Controller board (EVAL-SDP-CS1ZEVAL-SDP-CS1Z) for connection to the PC. The SDP controller board connects to the PC via USB 2.0. The evaluation board will connect to the SDP controller board. The evaluation board cannot be connected directly to the PC. The evaluation software running on the PC will communicate with the evaluation board through the SDP Controller board.
Key Applications: Mechanical potentiometer replacement, Portable electronics level adjustment, Audio volume control, Low resolution DAC, LCD panel brightness and contrast control, Programmable voltage to current conversion, Programmable filters, delays, time constants, Feedback resistor programmable power supply, Sensor calibration | |||||||||||
