STLC3055Q vs STLC3055N compatibility.
STLC3055N is pin to pin compatible with the old STLC3055Q but offer a better performance
in term of power consumption and can be set in a new gain configuration in order to be
compatible with the 3.3 V codec.

Active on hook
Ring (no REN)
To meet this result some differences, with a minimum impact on the application, has been
introduced in STLC3055N.

Hardware differences
●
RX input. In STLC3055N it is necessary a 100 kΩ external resistor between RX input
and AGND to bias the input stage.
Rp. The STLC3055N required a Rp value of 50 Ω instead of 41 Ω.
●
●
TTX filter. To optimize the ttx signal dynamic, the values of RLV and CFL have been
changed;
