Полупроводники - Микросхемы\Цифровые Потенциометры\Энергонезависимые Цифровые ПотенциометрыAD5254 is a quad channel 256 position I²C non-volatile memory digital potentiometer. It perform the same electronic adjustment functions as mechanical potentiometers, trimmers, and variable resistors. The parts' versatile programmability allows multiple modes of operation, including read/write access in the RDAC and EEMEM registers, increment/decrement of resistance, resistance changes in ±6dB scales, wiper setting readback, and extra EEMEM for storing user-defined information, such as memory data for other components, lookup table, or system identification information. It is widely used in application such as mechanical potentiometer replacement, low resolution DAC replacement, RGB LED backlight control, white LED brightness adjustment, RF base station power amp bias control, programmable gain and offset control, programmable attenuators, programmable voltage-to-current conversion, programmable power supply, programmab
