Product specification
1 W BTL mono audio amplifier with DC
volume control
TDA7052A/AT
CHARACTERISTICS
VP = 6 V; Tamb = 25 °C; f = 1 kHz; TDA7052A: RL = 8 Ω; TDA7052AT: RL = 16 Ω; unless otherwise specified (see Fig.6).
Notes to the characteristics
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) at f = 500 kHz is measured with RS = 0 Ω and bandwidth = 5 kHz.
3. The ripple rejection is measured with RS = 0 Ω and f = 100 Hz to 10 kHz. The ripple voltage of 200 mV, (RMS value)
is applied to the positive supply rail.
4. The noise output voltage (RMS value) is measured with RS = 5 kΩ unweighted.
