Low power audio DAC UDA1334BT
9 LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134).
Note
1. All supply connections must be made to the same power supply.
2. Short-circuit test at T

= 3 V. DAC operation after short-circuiting cannot be warranted.
10 HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, it is good practice to take
normal precautions appropriate to handling MOS devices.
