The ADN4654/ADN4655/ADN46561? are signal isolated, low voltage differential signaling (LVDS) buffers that operate at up to 1.1 Gbps with low jitter. The devices integrate Analog Devices, Inc., iCoupler? technology, enhanced for high speed operation to provide galvanic isolation of the TIA/EIA-644-A compliant LVDS drivers and receivers. This integration allows drop-in isolation of an LVDS signal chain.The ADN4654/ADN4655/ADN4656 comprise multiple channel configurations, and the LVDS receivers on the ADN4655 and ADN4656 include a fail-safe mechanism to ensure a Logic 1 on the corresponding LVDS driver output when the inputs are floating, shorted, or terminated but not driven.For high speed operation with low jitter, the LVDS and isolator circuits rely on a 2.5 V supply.

Demonstration Circuit DC1702A is a Li-Ion/Polymer Shunt Battery Charger system with Low Battery Disconnect featuring the LTC4071EDDB. The LTC4071 allows simple charging of Li-Ion/Polymer batteries from very low current, intermittent or continuous charging sources. The DC1702 provides up to 50mA of output current at 4.1V from a 10V to 16V input supply. A near-zero current low battery latching disconnect function protects even the lowest capacity batteries from deep discharge and potentially irreparable damage. The 550nA to 50mA operating current makes charging possible from previously unusable sources. With its low operating current the LTC4071 is well suited to charge low capacity Li-Ion or thin film batteries in energy harvesting applications.
