E-STLC3085 - Integrated Pots Interface for Home Access Gateway and WLL - ST-Microelectronics Datasheet

Description
The STLC3085 is a SLIC device specifically designed for WLL (Wireless Local Loop), and ISDN Terminal Adaptors and VoIP applications. One of the distinctive characteristic of this device is the ability to operate with a single supply voltage (from +4.5V to +12V) and self generate the negative battery by means of an on chip DC/ DC converter controller that drives an external MOS switch.
