Original In Stock, ADI AD5254BRUZ50 Quad 256-Position Digital Potentiometers

Shenzhen Mingjiada Electronics Co., Ltd.——Long Term Supply ADI (AD5254BRUZ50) Quad 256-Position I2C Nonvolatile Memory, Digital Potentiometer (DigiPOT).

AD5254BRUZ50——Basic Information:

Part Number: AD5254BRUZ50
Package: TSSOP-20
Type: Digital Potentiometer (DigiPOT)
Product Details: AD5254BRUZ50——Quad-channel, I2C, nonvolatile memory, digitally controlled potentiometers with 64/256 positions, respectively.

AD5254BRUZ50 is quad-channel, I2C, nonvolatile memory, digitally controlled potentiometers with 64/256 positions, respectively.

AD5254BRUZ50 perform the same electronic adjustment functions as mechanical potentiometers, trimmers, and variable resistors.

AD5254BRUZ50's versatile programmability 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 readback, and extra EEMEM for storing user-defined information, such as memory data for other components, look-up table, or system identification information.

AD5254BRUZ50 allow the host I2C controllers to write any of the 64-/256-step wiper settings in the RDAC registers and store them in the EEMEM. Once the settings are stored, they are restored automatically to the RDAC registers at system power-on; the settings can also be restored dynamically.

AD5254BRUZ50 provide additional increment, decrement, +6 dB step change, and –6 dB step change in synchronous or asynchronous channel update mode. The increment and decrement functions allow stepwise linear adjustments, with a ± 6 dB step change equivalent to doubling or halving the RDAC wiper setting. These functions are useful for steep-slope, nonlinear adjustments, such as white LED brightness and audio volume control.

AD5254BRUZ50 have a patented resistance-tolerance storing function that allows the user to access the EEMEM and obtain the absolute end-to-end resistance values of the RDACs for precision applications.
