Ag2130 is a low cost single channel PSTN Interface in a SIL package. The module provides many integrated features, including a basic barrier on-chip. It can be used in systems without a ground, or in applications where common mode interference is very high. Ag2130 can also be operated from either +3.3V or a +5V supply.

The Ag2120 is a self-contained highly integrated PSTN Interface Circuit in a single SIL or DIL module, which complies with RoHS requirements
