2
× 2.2 W BTL audio amplier
[1]
With a load connected at the outputs the quiescent current will increase, the maximum of this increase being equal to the DC output
offset voltage divided by RL.
[2]
The DC output voltage with respect to ground is approximately 0.5
× V
CC.
12. Dynamic characteristics
[1]
Gain of the amplier is 2
× (R2 / R1) in test circuit of Figure 3.
[2]
The noise output voltage is measured at the output in a frequency range from 20 Hz to 20 kHz (unweighted), with a source impedance
of RS =0 at the input.
[3]
Power supply rejection ratio is measured at the output with a source impedance of RS =0 at the input. The ripple voltage is a
sine wave with a frequency of 1 kHz and an amplitude of 100 mV (RMS), which is applied to the positive supply rail.
[4]
Power supply rejection ratio is measured at the output, with a source impedance of RS =0 at the input. The ripple voltage is a
sine wave with a frequency between 100 Hz and 20 kHz and an amplitude of 100 mV (RMS), which is applied to the positive supply rail.
[5]
Output voltage in mute position is measured with an input voltage of 1 V (RMS) in a bandwidth of 20 kHz, which includes noise.
