between VCCA, VCCO and VCCD is between −1 V and +1 V.
HANDLING
Inputs and outputs are protected against electrostatic discharges in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling integrated circuits.

The analog and digital supplies should be separated and decoupled.
VRT(n), VRM(n) and VRB(n) and DEC inputs are decoupled to AGND.
(1) In the event of AC-coupling, CLA and CLB values are chosen in accordance with the classical low frequencies cut-off formulae
fCL = 2-----×-----π-----×---1--R----I---×-----C----L- where input resistance RI is the value measured under DC conditions.
In the event of DC-coupling, CLA and CLB capacitors are omitted. The DC biassing and AC modulation signal directly applied to inputs (pin 6 and 11),
must be in the range of VRT(n) − VRB(n).
(2) When pin 10 (DEC) is short-circuited to AGND, an external regulator can be connected to VRT(n) and VRB(n).
