Notes
1. The channel separation is determined by the parasitic capacitance between the inverting input left channel (pin 4)
and the inverting input right channel (pin 5). The PCB layout has a major contribution to the parasitic capacitance.
To obtain best results the PCB tracks to pin 4 and pin 5 should be separated as much as possible.
2. The frequency response is externally fixed by the input coupling capacitors.
3. Noise output voltage is measured in a bandwidth of 20 Hz to 20 kHz with a source resistor Rs = 600 Ω.
4. Noise output voltage is measured in a bandwidth of 20 Hz to 20 kHz with an A-weighted filter with a source resistor
Rs = 600 Ω.
5. Distortion is measured at a frequency of 1 kHz using an A-weighted filter.
6. Distortion is measured at an output voltage of 3.0 V (RMS) at frequencies between 17 Hz and 20 kHz.
7. Ripple rejection is measured at the output, using a source resistor Rs = 600 Ω and a ripple amplitude of
100 mV (RMS) at a frequency of 1 kHz.
8. Ripple rejection is measured at the output, using a source resistor Rs = 600 Ω and a ripple amplitude of
100 mV (RMS) at frequencies between 20 Hz and 20 kHz.
