آی سی پتانسیومتر یک مقاومت متغیر دیجیتالی است که از آرایه ای از مقاومت ها ساخته شده و دارای بخش کنترلی است و از طریق اینترفیس سه سیمه قابل کنترل می باشد.
پتانسیومتر دیجیتالی X9C102S به صورت SMD و با مقدار اهمی یک کیلو اهم، از طریق پالس های
الکتریکی قابل تغییر است و در کاربردهایی مانند تغییر حجم صدا و ساخت پالس استفاده می شود.
Description:
The X9C102, X9C103, X9C104, X9C503 are digitally controlled (XDCP) potentiometers. The device consists of a resistor array, wiper switches, a control section, and nonvolatile memory. The wiper position is controlled by a three-wire interface.
The potentiometer is implemented by a resistor array composed of 99 resistive elements and a wiper switching network. Between each element and at either end are tap points accessible to the wiper terminal. The position of the wiper element is controlled by the CS, U/D, and INC inputs.
The position of the wiper can be stored in non-volatile memory and then be recalled upon a subsequent power-up operation.
The device can be used as a three-terminal potentiometer or as a two-terminal variable resistor in a wide variety of applications ranging from control to signal processing to parameter adjustment.
Application:
for the storage of multiple potentiometer settings or data
computer-based digitally controls
