Dual Potentiometer Eyes Gbit Transceivers

The DS1845 is said to be the industry's first dual potentiometer with integrated memory, specifically designed for use with gigabit transceiver modules. The device combines two linear-taper potentiometers with a 256-byte EEPROM and in-circuit programmability via a two-wire interface.
Users configure the device's dual 100-position and 256-position outputs with application-specific settings that are stored in nonvolatile memory. By integrating memory with two differently configured potentiometers, a single device replaces multiple parts. The interface allows drop-in compatibility with existing software written for standard two-wire EEPROM as well as circuit updates. In a TSSOP, pricing is $1.73 each/1,000.
