UNBALANCED TO BALANCES SIGNAL CONVERTER
FEATURES
The TA2026SN, TA2026F are unbalanced to balanced TA20265N
signal converter k: for component type car audio
equipments. Noise level of audio signal increases by
ground noise and induction noise while transfered
between head unit and other equipments.
To reduce these effect, balanced signal transfer system is
effective.
TA2026SN, TA2026F have built-in dual balanced signal
output amplifier and audio muting circuit.
In application with ground isolator Ic ; TA8181SN, SSlP12-P-1.78
TA8181F for line input stage, high performance balanced
signal transfer system can be composed.
