DESCRIPTION  
The DS1845 Dual NV Potentiometer and Memory consists of one100-position linear taper  
potentiometer, one256-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. Access to this EEPROM is via an  
industry standard 2-wire bus. The wiper position of the DS1845, as well as EEPROM data, can be  
hardware write-protected using the Write Protect (WP) input pin. Up to eight DS1845s can be installed  
on a single 2-wire bus. Access to an individual device is achieved by using a device address that is  
determined by the logic levels of address pins A0 though A2. Additionally, the DS1845 will operate  
from 3 volt or 5 volt supplies. Three package options are available: Flip Chip Package, 16-ball CSBGA  
and 14-pin TSSOP.
