Audio Power Amplifier IC
TK17119Y
DESCRIPTION
The TK11719Y is audio amplifier capable of low
voltage operation for speaker drivers.
The coupling capacitors to the speaker are not required ,
because of BTL (Bride) configuration.
Current consumption can be decreased by the stand-by
function.
FEATURES
! Low Voltage Operation Available
Vcc=1.8V
18V
! Low Current Consumption
Icc=2.7mA (Vcc=3.6V, R
L=∞)
! Stand-by Function Available
Iccs=1.0
A max.
! Maximum Output Power

OM=280mW
(Vcc=5.0V, R
L=32)
! Equivalent for MC34119,NJM2135
APPLICATIONS
! Suitable for speaker drive of a portable equipment.
