Overview

The DS1845E-010 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 DS1845E-010 will operate from 3 volt or 5 volt supplies. Three package options are available: Flip Chip Package, 16-ball CSBGA and 14-pin TSSOP.
