1W BTL MONO AUDIO
AMPLIFIER WITH DC VOLUME
CONTROL
DIP-8
DESCRIPTION
The UTC TDA7052A is mono BTL output amplifier with DC
volume control. It is designed for use in TV and monitors,
additionally it is suitable for portable recorders and radios.
In the IC, a Missing Current Limiter (MCL) is built-in. This
function is activated when the difference of current between the
OUT+ and OUT- exceed 100mA (typical 300mA). This level of
100mA suit for headphone applications (single-ended).
SOP-8
FEATURES
* Low power consumption
* DC volume control
* Mute mode
* No switch-on and off clicks
* Short-circuit proof
* Good overall stability
* Low HF radiation
* Few external components
* Thermal protection
* ESD protected on all pins
* Missing Current Limiter (MCL)

Notes: 1. With a load connected to the outputs the quiescent current will increase, the maximum value of this
increase being equal to the DC output offset voltage dividend by RL.
2. The noise output voltage (RMS value) is measured with RS=5kΩ unweighted.
3. The noise output voltage (RMS value) at f=500kHz is measured with RS=0Ω and bandwidth=5kHz.
4. The ripple rejection is measured with RS=0Ω and f=100Hz~10kHz. The ripple voltage of 200mV, (RMS
value) is applied to the positive supply rail.
