EQUIVALENT SCHEMATIC

DESCRIPTION

The TPA12 and TPA12A are designed for high

voltage and high current applications. They can

deliver up to 600 Watts of power to a load. The

safe operating area (SOA) at the output stage can

be guaranteed for all operating conditions by

properly selecting the external current limiting

resistor.

The class A/B output stage delivers power with

remarkably low distortion (see graph page 3). In

order to maintain stable bias current and low

distortion over the operating temperature range a

resistor/thermistor network in the V_BEmultiplier is

used to closely match the V_BEof the output

transistors.
