DESCRIPTION The Ag2120 is a self-contained highly integrated PSTN Interface Circuit in a single SIL or DIL module, which complies with RoHS requirements. In addition to the features listed, the Ag2120 allows flexible programming of many functions, including the dc voltage mask and impedances. The Ag2120 meets international safety and regulatory requirements. The device requires a minimum of external components and has been specified for ease of use, to allow reduced time to market. The Ag2120 is designed for all applications, including those where there is a high level of common mode interference, such as PABX, long loop applications and systems without a ground connection.
