Data Sheet AS2523, AS2524, AS2524B
Tone mode
This mode is used to send DTMF and FSK data to the line.
Speech mode is Tone mode (M1-M2;M3-M4 muted, Rx path muted, RO and LO active)
Loudhearing AS2524 and AS2524B (feature only available as DIE)
Speech mode is Loudhearing (M3-M4, RO active; LO activated).
Loudhearing can be activated via a bond-option (see document “AS2523/24 Delivery as Dice”).
Electrical characteristics
Electrical characteristics are measured with the Test Circuit
application. Typical mean values will not be tested.
