Low CostWide Supply Voltage Range: 5V to 40VHigh Output Current: 3A MinimumHigh Efficiency: Vs-2.2V at 2.5AInternal Current LimitWide Common Mode Range(Includes Negative Supply Voltage)Low DistortionInternal Output Snubbers for Ultra-Stable OperationThe MSK 105 is a high power quad operational amplifier. Each amplifier is capable of delivering three amps ofcurrent to the load. The MSK 105 is an excellent low cost alternative for bridge mode configurations since allamplifiers are packaged together and will track thermally. The wide common mode range includes the negative rail, facilitating single supply applications. It is possible to have a "ground based" input driving a single supply amplifierwith ground acting as the second or "bottom" supply of the amplifier. To maintain stability, output snubber networkshave been internally connected to each op amp output (see "amplifier stability" in the attached application notes).The output stage is also current limit protected to approximately 3.0 amps. The MSK 105 is packaged in a spaceefficient 18-pin ceramic dip. Consult factory for other packaging options if desired.

Operates In Class AB Or Class C ModeLow CostHigh Voltage Operation : 150VLow Quiescent Current : 8.0 mA Total Typ. In Class "C" ModeHigh Output Current : 5A Min. Per AmplifierNo Second BreakdownHigh Speed : 27VS Typ.External Compensation For Optimum Gain-Bandwidth The MSK 101 is a dual high power monolithic MOSFET operational amplifier ideally suited for high power amplificationand magnetic deflection applications. With a total supply voltage rating of 150 volts and 5A of output currentavailable from each amplifier, the MSK 101 is also an excellent low cost choice for motor drive circuits. The MOSFEToutput frees the MSK 101 from secondary breakdown limitations and power dissipation is kept to a minimum with atypical quiescent current rating of only 8.0 mA total in class "C" mode. Power saving class "C" mode is enabledby the user externally. The MSK 101 is packaged in a hermetically sealed 18 pin ceramic dip which has two externalcompensation pins for each amplifier.
