TFA9843AJ
20 W stereo power amplifier with volume control
4. Quick reference data
[1] A minimum load of 3 Ω is allowed at supply voltages > 22 V.
[2] Supply voltage ripple rejection is measured at the output, with a source impedance Z
S
=0Ω at the input
and with a frequency range from 20 Hz to 22 kHz (unweighted). The ripple voltage is a sine wave with a
frequency f
ripple
and an amplitude of 300 mV (RMS), which is applied to the positive supply rail.
