Description

General part information

AD5252 Series

The AD52521is a dual-channel, I2C, nonvolatile memory, digitally controlled potentiometer with 256 positions. These devices 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 ±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.The AD5251/AD5252 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.The AD5251/AD5252 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.The AD5251/AD5252 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.The AD5251/AD5252 are available in TSSOP-14 packages. AD5251 has only 50 kΩ resistance options and AD5252 is available in 1 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ options. All parts are guaranteed to operate over the –40°C to +105°C extended industrial temperature range.ApplicationsMechanical potentiometer replacementGeneral-purpose DAC replacementLCD panel VCOMadjustmentWhite LED brightness adjustmentRF base station power amp bias controlProgrammable gain and offset controlProgrammable voltage-to-current conversionProgrammable power supplySensor calibrations1Protected by U.S. Patent 7,688,240.
