*Note: All minimum and maximum specifications are guaranteed and apply across the recommended operating conditions.

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 level of any unwanted tones within the bandwidth of 0 to 4 kHz does not exceed –55 dBm.

3. Assumes normal distribution of betas.
