Audio Power Amplifier IC
TK17119F
1. DESCRIPTION
The TK17119F is an audio power amplifier IC capable of
low voltage operation. Coupling capacitors to the speaker
are not required, because of BTL (Bridged Tied Load)
configuration. Its very small SON-8 package is excellent
for small space requirements. Built-in stand-by function
can reduce supply current at stand-by mode. Therefore, it
is suitable for any battery-powered portable equipment.
2. FEATURES
!
Low operating voltage range: VCC=2.0 to 16V
!
Low supply current: ICC=2.7mA(VCC=3.0V)
!
Stand-by function: ICCS<1A
!
Maximam output power: POMAX=400mW(TYP)
(VCC=6V, RL=32)
!
Low total harmonic distortion: THD=0.5%
3. APPLICATIONS
!
Speaker drive
!
DC motor drive(forward, reverse)
!
Other general use
