Preliminary data sheet Rev. 01 — 1 December 2005 5 of 19 Philips Semiconductors SA58631 3 W BTL audio amplifier 11. Static characteristics [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 amplifier 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 Ω at the input. [3] Supply voltage ripple rejection is measured at the output with a source impedance of Rs =0 Ω 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] Supply voltage ripple rejection is measured at the output, with a source impedance of Rs = 0 Ω 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.
