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. 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.
