∗1 The crosstalk between TAPE and AUX is measured with a 5.1kΩ external resistor connected to AUXIN1

(Pin 5). In this condition, the crosstalk is approximately –67dB due to the signal leak from MSLPF (Pin 6).

In order to improve the crosstalk between TAPE and AUX, AUXIN1 pin should be driven with a low

impedance.
