The maximum gain Gtl is adjustable between 44

The AGC variation is programmed with one resistor
connected on Pin AGC. ISL is the line current at
which the gain must be decreased by 6dB.

− 5mA
(R25 > 2.6k
Ω)
For line current lower than ILL or higher than ISL,
The transmit and receive gains have a constant
value.
If no resistor or a resistor higher than 300k
Ω is
connected on Pin AGC, the gain is constant and
equal to Gtxl and Grxl.
±0.5dB.
AGC can be inhibited also through MCU code
”010100”. In this case Tx and Rx gains are fixed
2dB lower than the maximum gain.
The minimum saturation voltage of the TEA7089A
respect to ground is 2.2V. On long line, when the
voltage over TEA7089A is low, the softclipping
function automatically limits the AC dynamic to
avoid to reach the 2.2V limit on TEA7089A respect
to ground.
