MAXIM INTEGRATED PRODUCTS  MAX5401EKA+T  易失性数字电位器, 低漂移, 100 kohm, 单, SPI, 线性, ± 25%, 2.7 V

The is a 256-tap SOT-PoT low-drift digital potentiometer in 8 pin SOT-23 package. This volatile digital potentiometer includes a fixed resistor string with a digitally controlled wiper contact. It provides glitchless switching between resistor taps as well as a convenient power-on reset that sets the wiper to the midscale position-128 at power-up. MAX5401 serves well in applications requiring digitally controlled resistors including adjustable voltage references and programmable gain amplifiers PGAs.
