Notes :

1. DC offset change is less than maximum limit, in all configurations (one or several devices in parallel), provided that the

reference Pins (P2) are all connected together.

2. Flat filter according to CCIR-468-4, B = 20Hz-20kHz

3. Measured from any selected output which contains no signal to a set of other outputs.
