TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8201AK
BTL Audio Power Amplifier
TA8201AK
The TA8201AK is a audio power amplifier for consumer
application.
This IC is applying BTL system in which output coupling
condenser and bootstrap condenser are not necessary and output
17W (VCC = 14.4V, BL =4Ω, THD = 10%) can be obtained.
Since the package is a 7 pin SIP, (signal inline package), it
greatly simplifies construction of a power amplifier both in design
and assembly.
It also contains various kind of protector.
It is suitable for car−audio power amplifier with high
performance.
Features
· High power: POUT (1) = 17W (typ.)
(VCC = 14.4V, f = 1kHz, THD = 10%, RL = 4Ω)
: POUT (2) = 14W (typ.)
(VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4Ω)
· Very few external parts
· Built in protector circuit
Thermal shut down, over voltage protector (typ. VCC = 24V)
ASO protector (RL short, Out to GND, Out to VCC)
· 7 pin small package
· Operating supply voltage range: VCC = 9~18V
Weight: 2.19g (typ.)
