Typical values apply at nominal supply voltages and an operating temperature of 25 oC unless otherwise stated.
Product specifications are only guaranteed when the typical application circuit (including component tolerances) is
used.

Notes:
1. Analog signal measured as VTIP – VRING. Assumes ideal line impedance matching.
2. The quantization errors inherent in the µ/A-law companding process can generate slightly worse gain tracking
performance in the signal range of 3 dB to –37 dB for signal frequencies that are integer divisors of the 8 kHz PCM
sampling 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.
