4 MHz bandwidth—1 kΩ version  
Single supply 2.7 V to 5.5 V  
Dual supply 2.25 V to 2.75 V  
2 slave address decoding bits allow operation of 4 devices  
100-year typical data retention, TA = 55°C  
Operating temperature: –40°C to +105°C  
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.  
APPLICATIONS  
Mechanical potentiometer replacement  
General-purpose DAC replacement  
LCD panel VCOM adjustment  
White LED brightness adjustment  
RF base station power amp bias control  
Programmable gain and offset control  
Programmable voltage-to-current conversion  
Programmable power supply  
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.  
Sensor calibrations  
GENERAL DESCRIPTION  
The AD5251/AD5252 are dual-channel, I2C®, nonvolatile mem-  
ory, digitally controlled potentiometers with 64/256 positions,  
respectively. These devices perform the same electronic adjust-  
ment 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 are available in TSSOP-14 packages 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.  
1 The terms nonvolatile memory and EEMEM are used interchangeably.  
2 The terms digital potentiometer and RDAC are used interchangeably.
