Amplifier:

Attention:

In the POWER 2001 module the power amplifier IC AN

0A

is used as a bridge-amplifier.

Any connection from output to ground will destroy the outpout stages!

•

Via the AMP_ON control line, connected to pins 6 (Stby), the power amplifiers are switched on/off by the µP.
High level (approx. 4,5V): power amplifiers switched on
Low level (approx. 0V): power amplifiers switched off

•

Super class G - operation

The power amplifiers operate as so-called super class G - amplifiers:
The supply pins 12 (Vcc) are not just connected to one fixed DC-supply as in conventional amplifiers.
Dependent on the output power there are three different DC-voltages supplied to the power amplifiers:

⇒

+C1 (+20V) for low output power

⇒

+B1 (+29V) for medium output power

⇒

+A1 (+41V for high output power
