The AD5121/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 RAW and RWB string 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.

Product Detail
The AD5141 allows multiple modes of operation, including read/write access in the RDAC and EEMEM registers, increment/decrement of resistance, resistance changes in ±6 dB scales, wiper setting read-back, and extra EEMEM for storing user-defined information, such as memory data for other components or a lookup table.
The AD5141 supports a dual-supply ±2.25 V to ±2.75 V operation and a single-supply 2.3 V to 5.5 V operation, making the device suitable for battery-powered applications and many other applications. In addition, the AD5141 can be configured as a versatile I2C or SPI serial interface. The EVAL-AD5141DBZ can operate in single-supply or dual-supply mode and incorporates an internal power supply from the USB.
Complete specifications for the AD5141 can be found in the AD5141 datasheet.
