产品概述

The DS1845 Dual NV Potentiometer and Memory consists of one 100-position linear taperpotentiometer, one 256-position linear taper potentiometer, 256 bytes of EEPROM memory, and a 2-wireinterface. The device provides an ideal method for setting bias voltages and currents in controlapplications using a minimum of circuitry. The EEPROM memory allows a user to store configurationor calibration data for a specific system or device as well as provide control of the potentiometer wipersettings. Any type of user information may reside in the first 248 bytes of this memory. The next twoaddresses of EEPROM memory are for potentiometer settings. Access to this EEPROM is via anindustry standard 2-wire bus. The wiper position of the DS1845, as well as EEPROM data, can behardware write-protected using the Write Protect (WP) input pin. Up to eight DS1845s can be installedon a single 2-wire bus. Access to an individual device is achieved by using a device address that isdetermined by the logic levels of address pins A0 though A2. Additionally, the DS1845 will operatefrom 3 volt or 5 volt supplies. Three package options are available: Flip Chip Package, 16-ball CSBGAand 14-pin TSSOP.
