Description
General part information
AD5141 Series
TheAD5121/AD5141 potentiometers provide a nonvolatile solution for 128-/256-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 low resistor tolerance and low nominal temperature coefficient simplify open-loop applications as well as applications requiring tolerance matching.The linear gain setting mode allows independent programming of the resistance between the digital potentiometer terminals, through RAWand RWBstring resistors, allowing very accurate resistor matching.The high bandwidth and low total harmonic distortion (THD) ensure optimal performance for ac signals, making it suitable for filter design.The low wiper resistance of only 40 Ω at the ends of the resistor array allows for pin-to-pin connection.The wiper values can be set through an SPI-/I2C-compatible digital interface that is also used to read back the wiper register and EEPROM contents.The AD5121/AD5141 is available in a compact, 16-lead, 3 mm × 3 mm LFCSP. The devices are guaranteed to operate over the extended industrial temperature range of −40°C to +125°C.ApplicationsPortable electronics level adjustmentLCD panel brightness and contrast controlsProgrammable filters, delays, and time constantsProgrammable power supplies
