UTC TA8229 LINEAR INTEGRATED CIRCUIT
UTC UNISONIC TECHNOLOGIES CO., LTD. 1
QW-R107-028,A

LOW FREQUENCY POWER
AMPLIFIER

DESCRIPTION
The UTC TA8229 is an audio power IC with built-in
two channels developed for portable radio cassette tape
recorder with power ON/OFF switch.
Because of the parts reduction and SIP (Single Inline
Package), space merit is remarkable.
Thermal shut down protection circuit is buit in.

FEATURES
* High Power
: Pout (1) = 2.5W (Typ.)
(VCC = 9V, RL = 4Ω, f = 1kHz, THD = 10%)
: Pout (2) = 4.6W (Typ.)
(VCC = 12V, RL = 4Ω, f = 1kHz, THD = 10%)
* Low Popping Noise at Power ON
* Small Quiescent Current
: ICCQ = 21mA (Typ.) (VCC = 15V, Vin = 0)
* Soft Clip
* Built-in Thermal Shut Down Protection Circuit
* Best for Supply Voltage 9V, 12V
* Operation Supply Voltage Range : VCC (opr) = 6 ~ 15V
(Ta = 25℃ )
