IL9270 - DTMF Receiver

NAME PIN ESt 16 GS IC IN+ INC1 C2 Q1-Q4 StD 3 5,6 1 2 7 8

TECHNICAL DATA DTMF RECEIVER High-Performance Silicon-Gate CMOS IL9270 The IL9270N/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.

Digital counting techniques are employed in the decoder to detect and decode all 16 DTMF tone-pairs into a 4-bit code.

External component count is minimized by on-chip provision of a differential input amp
