DESCRIPTION  
The DS1845 Dual NV Potentiometer and Memory consists of one=100-position linear taper  
potentiometer, one=256-position linear taper potentiometer, 256 bytes of EEPROM memory, and a 2-wire  
interface. The device provides an ideal method for setting bias voltages and currents in control  
applications using a minimum of circuitry. The EEPROM memory allows a user to store configuration  
or calibration data for a specific system or device as well as provide control of the potentiometer wiper  
settings. Any type of user information may reside in the first 248 bytes of this memory. The next two  
addresses of EEPROM memory are for potentiometer settings and the remaining 6 bytes of memory are  
reserved. These reserved and potentiometer registers should not be used for data storage. Access to this  
EEPROM is via an industry standard 2-wire bus. The interface I/O pins consist of SDA and SCL. The  
wiper position of the DS1845, as well as EEPROM data, can be hardware write-protected using the Write  
Protect (WP) input pin.
