TPA12

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 – 1.4 oC/W 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 used to closely match the transistors. tVheBEVBoEf multiplier is the output EXTERNAL CONNECTIONS AND PIN CONFIGURATIONS RCL+ CL+ +Vs 3 2 1 OUT +IN 4 TOP VIEW -IN 5 6 8 7 CL- RCL- -Vs F.O.
