Notes:
1. Measured at TIP and RING with 600
Ω termination at 1 kHz.
2. R2 should be changed to a 243
Ω resistor when the SF5[7] (FULL) = 1
b.
3. DR
= 20 x log |Vin| + 20 x log (RMS signal/RMS noise).
4. Measurement is 300 to 3400 Hz. Applies to both transmit and receive paths.
5. Vin
= 1 kHz, –3 dBFS, Fs = 10300 Hz.
6. ACT
= SF5[4]; DCT = SF5[3:2].
7. Vin
= 1 kHz, –6 dBFS, Fs = 10300 Hz.
8. THD
= 20 x log (RMS distortion/RMS signal).
9. VCM can be improved to 120 Vrms minimum by placing a 20 MΩ resistor across the C9 capacitor.
