AC Characteristics (Continued)(VDDA, VDDD = 3.13 to 5.25 V, TA = 0 to 70°C for K-Grade, –40 to 85°C for B-Grade)ParameterTest ConditionMinTypMaxUnitNotes:1. Analog signal measured as VTIP – VRING. Assumes ideal line impedance matching.2. The quantization errors inherent in theµ/A-law companding process can generate slightly worse gain trackingperformance in the signal range of 3 dB to –37 dB for signal frequencies that are integer divisors of the 8 kHz PCMsampling rate.3. The level of any unwanted tones within the bandwidth of 0 to 4 kHz does not exceed –55 dBm.4. Assumes normal distribution of betas.
