Product Summary
The STLC3055NAF is a WLL & ISDN-TA subscriber line interface circuit specifically designed for WLL (Wireless Local Loop) and ISDN Terminal Adaptors and VoIP applications. One of the distinctive characteristic of the STLC3055NAF device is the ability to operate with a single supply voltage (from +5.5V to +12V) and self generate the negative battery by means of an on chip DC/DC converter controller that drives an external MOS switch.
