Input DC biasing

Input DC bias is maintained at ground level.

If the input signal contains DC bias voltage,

AC coupling should be included on the

application circuit.

The value of 20kΩ resistor is set in order to

achieve the minimum output DC offset.

Output Zobel Network

It should be noted that this device is

designed such that the Zobel network (RC

pair) at the output pins is not necessary

for stable operation.

In practical application, the Zobel network

may be applied optionally for two reasons:

a) Ensuring stability for different PCB layout

and speaker types.

b) Ability to withstand to high ESD levels.
