DESCRIPTION

The MP230 operational amplifier is a surface mount con - structed component that provides a cost effective solution in many industrial applications. The MP230 offers outstanding performance that rivals many much more expensive hybrid components yet has a footprint of only 4.7 sq in. The MP230 has many optional features such as four-wire current limit sens ing, 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 MP230 is built on a thermally conductive but electrically insulating substrate that can be mounted to a heat sink. EQUIVALENT CIRCUIT DIAGRAM 42-PIN DIP PACKAGE TYPE FC TYPICAL APPLICATION MOTOR POSITION CONTROL The MOSFET output stage of the MP230 provides superior SOA performance compared to bipolar output stages where secondary breakdown is a concern. The extended SOA is ideal in motor drive applications where the back EMF of the motor may impose simultaneously both high voltage and high current across the output stage transistors. In the figure above a mechanical to electrical feedback position converter allows the MP230 to drive the motor in either direction to a set point determined by the DAC voltage. EXTERNAL CONNECTIONS

The value of the current limit resistor can be calculated as follows: RLIM = .65/ILIMIT BOOST OPERATION With the boost feature the small signal stages of the amplifier are operated at a higher supply voltages than the amplifier’s high current output stage. +V B (pin 1) and -V B (pin 38) are connected to the small signal stages. An additional 10V on the +VB and -VB pin is sufficient to allow the small signal stages to drive the output stage into the triode region and improve the output voltage swing for extra efficient operation when required. When the boost feature is not needed +V S and -VS are connected to +VB and -VB respectively. +VB and -VB must not be operated at supply voltages less than +V S and -VS respectively. OPERATING CONSIDERATIONSMP230 SHUTDOWN The output stage is turned off by applying a 5V level to HSD (pin 8) relative to LSD (pin 7). This is a non-latching circuit. As long as HSD remains high relative to LSD the output stage will be turned off. LSD will normally be tied to signal ground but LSD may float from -V B to +VB - 10V. Shutdown can be used to lower quiescent current for standby operation or as part of a load protection circuit. BIAS CLASS OPTION Normally pin 5 (Iq) is left open. But when pin 5 is connected to pin 6 (Cc1) the quiescent current in the output stage is dis- abled. This results in lower quiescent power, but also class C operation of the output stage and the resulting crossover distortion. In many applications, such as driving motors, the distortion may be unimportant and lower standby power dis sipation is an advantage.
