9.3.6
A 2-bit value to enable the digital de-emphasis filter.
Table 18 De-emphasis settings
10 LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134).
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
3. Equivalent to discharging a 200 pF capacitor via a 0.75 H series inductor.
4. DAC operation cannot be guaranteed after a short-circuit has occurred.
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.

9.3.7
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.
