APPLICATION NOTE 3481
Using the DS1859 with External
EEPROM
Abstract: This application note addresses adding external EEPROM into SFF-8472 applications that require
more than 128 Bytes of memory located at the IC* device address A0h.
Introduction
The DS1859 is a dual digital resistor that automatically adjusts itself as a function of temperature to the values
programmed into a EEPROM look-up table (LUT). Other features include five analog-to-digital channels (including
VCC and temperature) and a memory map that is compatible with SFF-8472 fiber optic applications. This
application note addresses adding ex
