9.3.6
DE-EMPHASIS
A 2-bit value to enable the digital de-emphasis filter.
Table 18 De-emphasis settings
9.3.7
OUTPUT POLARITY CONTROL
A 1-bit value to program the output polarity of the output
signal. This bit must be used together with the CH2 to CH0
bits and the ACH bit to either select the polarity for all
channels or to set for each channel individually.

10 LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
Notes
1. All supply connections must be made to the same power supply.
2. Equivalent to discharging a 100 pF capacitor via a 1.5 k
series resistor, expect pin 19 (L3DATA) which can
withstand ESD pulses of
2500 to +2500 V.
3. Equivalent to discharging a 200 pF capacitor via a 0.75
H series inductor.
11 HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling MOS devices.
12 THERMAL CHARACTERISTICS
13 QUALITY SPECIFICATION
In accordance with
“SNW-FQ-611-E”. The number of the quality specification can be found in the “Quality Reference
Handbook”.
