Notes:
DDA
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
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.
, V
Typical values apply at nominal supply voltages and an operating temperature of 25
Product specifications are only guaranteed when the typical application circuit (including component tolerances) is
used.
