‡ Typical figures are at 25 °C and are for design aid only: not guaranteed and not subject to production testing.
*
10. Referenced to lowest level frequency component in DTMF signal.
11. Referenced to the minimum valid accept level.
12. Guaranteed by design and characterization.

Gain Setting Amplifier
AC Electrical Characteristics
1. dBm= decibels above or below a reference power of 1 mW into a 600 ohm load.
2. Digit sequence consists of all DTMF tones.
3. Tone duration= 40 ms, tone pause= 40 ms.
4. Signal condition consists of nominal DTMF frequencies.
5. Both tones in composite signal have an equal amplitude.
6. Tone pair is deviated by ±1.5%± 2 Hz.
7. Bandwidth limited (3 kHz ) Gaussian noise.
8. The precise dial tone frequencies are (350 Hz and 440 Hz) ± 2 %.
9. For an error rate of better than 1 in 10,000.
