UA8229
LINEAR INTEGRATED CIRCUIT
LOW FREQUENCY POWER
AMPLIFIER
DESCRIPTION
The UTC UA8229 is a low frequency power amplifier and
developed for portable radio cassette tape recorder with power
ON/OFF switch.
The audio power IC has built-in two channels and thermal shut
down protection circuit.
HZIP-15A
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
: IQ = 21mA (Typ.) (VCC = 15V, VIN = 0)
* Soft Clip
* Thermal Shut Down Protection
* Best for Supply Voltage 9V, 12V
* Operation Supply Voltage Range from 6V to 15V

(*) This IC can be used without coupling capacitor (CIN).
If volume slide noise occurred by input offset voltage is undesirable, it needs to use the capacitor (CIN).
(**) The condenser between the pin 8 and the GND (C11) is for reducing POP noise when the power ON/OFF switch
(SW1) is set to ON/OFF.
