TPA12/ TPA12A
Power Operational Amplifier
THALER CORPORATION ⢠2015 N. FORBES BOULEVARD ⢠TUCSON, AZ. 85745 ⢠(520) 882-4000
FEATURES
⢠HIGH OUTPUT CURRENT - ±15A PEAK
⢠HIGH VOLTAGE RATING - ±50V
⢠LOW THERMAL RESISTANCE â 1.4 oC/W
â¢CURRENT FOLDOVER PROTECTION
⢠EXCELLENT LINEARITY - CLASS A/B OUTPUT
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 VBE multiplier is
used to closely match the VBE of the output
transistors.
