Functional Description

1. N-Channel Open Drain Output - DP, XMUTE

Figure 1.

2. DTMF Generator

The digitally synthesized sinewave of the

IN91260 series is well designed, with a 6 level,

12 segment, 1/2 VCC reference voltage. The THD

(Total Harmonic Distortion) of the DTMF output

is typically 1%, when VCC = 2.5 V to 5.5 V and

frequency is in the 500 HZ to 3400 HZ band.
