ADN2860:  3-Channel Digital Potentiometer with Nonvolatile Memory

Product Description

The ADN2860 contains three digitally controlled nonvolatile variable resistors with very low temperature drift. Packaged in a tiny 4 mm x 4 mm LFCSP package and designed to meet GBIC/MSA standard specifications, the ADN2860 is ideal for precision optical control applications.

The ADN2860 can be used in all SONET, SDH, ATM, and Gigabit Ethernet laser diode driver applications. This device can also be programmed to adjust temperature set-points in TEC controllers, APD bias supply, TIA gain settings, and optical power monitoring.

The ADN2860 can operate in single supply mode with supply voltages from 3 V to 5 V, or in dual supply mode with ±2.5 V supplies.

Features

  • Dual 9-bit & Single 7-bit Resolution 25 kΩ, 250 kΩ Terminal Resistance Options
  • 256 Bytes EEPROM Memory
  • 2-wire I2C Interface
  • Meets GBIC/MSA Specifications
