TDA7269
LINEAR INTEGRATED CIRCUIT
14W+14W STEREO AMPLIFIER
WITH MUTE & STAND-BY
DESCRIPTION
The UTC TDA7269 is a stereo 14+14W class AB Dual Audio
Power amplifier with mute and ST-BY control. This IC provides high
output power of 14 watts per channel (at VCC=±16V, f =1KHz, THD
= 10%, RL = 8 ). It has low IQ at stand-by mode and no POP at turn
ON or OFF.
FEATURES
* High output power: POUT =14 W/channel (Typ.)
VCC= ±16V, RL = 8, f =1KHz, THD = 10%
* Operation supply voltage range (Ta = 25°C)
VCC(OPR) = ±5~±20V (RL = 8 )
VCC(OPR) = ±5~±15V (RL = 4 )
* Split supply
* Built in overload protection circuit.
* Built in thermal shut down protector circuit.
* Built in audio muting circuit (POP free)
* Built in standby circuit.
