Description
IL2533AN, IL2533AD is CMOS IC, supporting all functions, necessary for design of electronic telephone with high characteristics.
Standard application circuit is shown at figure 2.
Features
- ─ Line/speech circuit. LD/MF constant automatic dialer
and tone ring at one 28-pin CMOS chip. ─ Operational range 13 to 100 mА (decreasing upto 5 mА
causes productivity deterioration). ─ Soft limitation for elimination of drastic distortion. ─ Controlling of received signal volume. ─ Automatic line loss compensation. ─ Low noise level (max.
- 72 dBmp). ─ Actual or complex impedance. ─ Switching LD/MF dialing. ─ Tone damper during programming. ─ Redial of the last 31 digit number. ─ Refere.
