These characteristics are determined by external components. See Figure 2 on page 6.
Parameter measured at Tip and Ring of Figure 2 on page 6.
Receive full scale level produces –0.9dBFS at SDO.
DR = 3dB + 20 log (RMS signal/RMS noise). Applies to both the transmit and receive paths. Measurement
bandwidth is 300Hz to 3400Hz. Sample rate = 9.6kHz; Loop current = 40mA.
DR = 3dB + 20 log (RMS signal/RMS noise). Applies to both the transmit and receive paths. Measurement
bandwidth is 15Hz to 3400Hz. Sample rate = 9.6kHz; Loop current = 40mA.
THD = 20 log (RMS distortion/RMS signal). Applies to both the transmit and receive paths. Sample rate = 9.6kHz;
Loop current = 40mA.
