Product Description

The AD5254BRUZ10 is a Quad 256-position I²C Compatible Non-volatile Memory Digital Potentiometer that performs the same electronic adjustment function 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, look-up table or system identification information. It allows the host I²C controllers to write 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. It provides additional increment, decrement, +6dB step change and -6dB step change in synchronous or asynchronous channel update mode.
Non-volatile memory stores wiper setting w/write protection
540µs Typical EEMEM rewrite time
Resistance tolerance stored in non-volatile memory
12 Extra bytes in EEMEM for user-defined information
Synchronous or asynchronous dual-channel update
2 Slave address decoding bits allow operation of 4 devices
ESD sensitive device, take proper precaution while handling the device.
