Philips Semiconductors Product specification
Stereo BTL audio output amplifier with DC
volume control TDA7053A
CHARACTERISTICS
VP=6V; T
amb =25°C; fi= 1 kHz; TDA7053A: RL=8Ω; TDA7053AT: RL=16Ω; unless otherwise specified
(see Fig.13).
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 divided by RL.
2. The noise output voltage (RMS value) at fi= 500 kHz is measured with RS=0Ω and bandwidth = 5 kHz.
3. 20 Hz to 300 kHz (typical).
4. The ripple rejection is measured with RS=0Ω and fi= 100 Hz to 10 kHz. The ripple voltage of 200 mV (RMS value)
is applied to the positive supply rail.
5. The channel unbalance is measured with VDC1 =V
DC2.
6. The channel unbalance at G1= 0 dB is measured with VDC1 =V
DC2.
7. The noise output voltage (RMS value) is measured with RS=5kΩ unweighted.
