It performs the same electronic adjustment function as a mechanical potentiometer with enhanced resolution, solid-state reliability, and remote controllability. The AD5231 features versatile programming using a standard 3-wire SPI-compatible serial interface supporting 16 modes of operation, including scratchpad programming, EEMEM storing and restoring, linear increment\/decrement, \u00b16 dB\/step log taper adjustment, and wiper setting readback. The EEMEM stores the wiper setting and automatically transfers it to the RDAC register at power-on in 140\u03bcs. An additional 28 bytes of EEMEM are available for user-defined data such as look-up tables or system identification. The REEL7 suffix indicates Tape & Reel packaging.","working_principle":"The AD5231 operates as a digitally controlled resistor with three terminals: A, B, and W (wiper). The 1024-position RDAC register controls the wiper position, dividing the total resistance (10k\u03a9) between W-A and W-B. The SPI interface receives 24-bit command words consisting of an instruction byte and a data byte. The scratchpad register allows direct wiper position programming without affecting EEMEM. The EEMEM stores the desired wiper position permanently and restores it automatically at power-on. Increment\/decrement commands move the wiper one step at a time without requiring full SPI data transfers. The \u00b16 dB commands double or halve the wiper setting for logarithmic adjustment. Write protection (WP) prevents accidental EEMEM modification, while the PR pin allows hardware EEMEM restore.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>VDD<\/td><td>PWR<\/td><td>Positive supply (2.7V-5.5V)<\/td><\/tr><tr><td>2<\/td><td>GND<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>3<\/td><td>VSS<\/td><td>PWR<\/td><td>Negative supply (dual supply mode)<\/td><\/tr><tr><td>4<\/td><td>A<\/td><td>Analog<\/td><td>Terminal A of resistor<\/td><\/tr><tr><td>5<\/td><td>W<\/td><td>Analog<\/td><td>Wiper terminal<\/td><\/tr><tr><td>6<\/td><td>B<\/td><td>Analog<\/td><td>Terminal B of resistor<\/td><\/tr><tr><td>7<\/td><td>RDY<\/td><td>O<\/td><td>Ready output (EEMEM operation status)<\/td><\/tr><tr><td>8<\/td><td>WP<\/td><td>I<\/td><td>Write protect (protects EEMEM)<\/td><\/tr><tr><td>9<\/td><td>PR<\/td><td>I<\/td><td>Program restore (hardware EEMEM recall)<\/td><\/tr><tr><td>10<\/td><td>CS<\/td><td>I<\/td><td>Chip select (active low)<\/td><\/tr><tr><td>11<\/td><td>SDI<\/td><td>I<\/td><td>SPI data input<\/td><\/tr><tr><td>12<\/td><td>SDO<\/td><td>O<\/td><td>SPI data output (wiper readback)<\/td><\/tr><tr><td>13<\/td><td>CLK<\/td><td>I<\/td><td>SPI clock<\/td><\/tr><tr><td>14<\/td><td>NC<\/td><td>-<\/td><td>No connect<\/td><\/tr><tr><td>15<\/td><td>NC<\/td><td>-<\/td><td>No connect<\/td><\/tr><tr><td>16<\/td><td>NC<\/td><td>-<\/td><td>No connect<\/td><\/tr><\/table>","application_scenarios":"<ul><li><b>Gain Adjustment<\/b>: Remote gain control of op-amp circuits in instrumentation and audio<\/li><li><b>Sensor Calibration<\/b>: Trim offset and span of sensor signal chains at production or in-field<\/li><li><b>Power Supply<\/b>: Programmable output voltage adjustment in lab and bench supplies<\/li><li><b>Filter Tuning<\/b>: Adjustable RC time constants for programmable filters and oscillators<\/li><li><b>LCD Contrast<\/b>: Nonvolatile contrast adjustment for LCD modules<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>AD5231BRUZ50<\/td><td>Analog Devices<\/td><td>50k\u03a9 resistance option<\/td><\/tr><tr><td>AD5231BRUZ100<\/td><td>Analog Devices<\/td><td>100k\u03a9 resistance option<\/td><\/tr><tr><td>AD5235BRUZ10<\/td><td>Analog Devices<\/td><td>Dual channel, 1024-position, 10k\u03a9<\/td><\/tr><tr><td>MCP4161-103E\/SN<\/td><td>Microchip<\/td><td>7-bit (129 pos), 10k\u03a9, SPI, 8-SOIC<\/td><\/tr><tr><td>AD8400ARZ10<\/td><td>Analog Devices<\/td><td>256-position, volatile, 10k\u03a9, simpler<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/2984","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=2984"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/2984\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=2984"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=2984"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=2984"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=2984"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
