简  介:P r o dMP240 u c t IIn nn no ov va a t i o n FFr room m MP240 MP240 GENERAL DESCRIPTION Power Operational Amplifier FEATURES LOW COST HIGH VOLTAGE - 200 VOLTS HIGH OUTPUT CURRENT - 20 AMPS 170 WATT DISSIPATION CAPABILITY The MP240 operational amplifier is a surface mount constructed component that provides a cost effective solution in many industrial applications. The MP240 offers outstanding performance that rivals much more expensive hybrid components yet has a footprint of only 4.7 sq in. The MP240 has many optional features such as four-wire current limit sensing, a shutdown control and external compensation. In addition, the class A/B output stage biasing can be turned off for lower quiescent current with class C operation in applications where crossover distortion is less important such as when driving motors, for example. A boost voltage feature biases the output stage for close linear swings to the supply rail for extra efficient operation. The MP240 is built on a thermally conductive but electrically insulating substrate that can be mounted to a heat sink.
