DC Electrical Characteristics are over recommended operating conditions, unless otherwise stated.
Typical figures are at 25
C and are for design aid only: not guaranteed and not subject to production testing.
AC Electrical Characteristics are over recommended operating conditions, unless otherwise stated.
Typical figures are at 25
C and are for design aid only: not guaranteed and not subject to production testing
*Notes:
1. Tip/Ring signal level. Input op-amp configured to 0dB gain at Vdd=5V+/-10%, -3.5dB at Vdd=3V+/-10%.
2. Tip/Ring signal level. Input op-amp configured to 0dB gain at Vdd=5V+/-10%.
3. Both tones have the same amplitude.
4. Band limited random noise 300-3400Hz. Measurement valid only when tone is present.
5. dBV - Decibels above or below a reference voltage of 1 Vrms. 0 dBV = 1 Vrms. Signal level is per tone.
6. dBm - Decibels above or below a reference power of 1 mW into 600 ohms. 0 dBm = 0.7746 Vrms. Signal level is per tone.
