SC9270
Overview
The SC9270C/D is a complete DTMF receiver integrating both the bandsplit filter and digital decoder functions. The filter section uses switched capacitor techniques for high- and low-group filters and dialtone rejection.
- Excellent performance * CMOS, single 5 volt operation, * Widely operating voltage: 1.2V ~ 5.25V * Minimum board area * Central office quality * Low power consumption * Power-Down mode (SC9270D only) * Inhibit-mode (SC9270D only)
