This amplifier offers large output currents, making it an excellent choice for motor drive circuits. The amplifier and load can be protected from fault conditions through the use of internal current limit circuitry that can be user programmed with two external resistors. These devices are also compensated with a single external capacitor. The MSK 106RH is packaged in a 20 pin hermetic metal flatpack that is available with straight or gull wing leads.

The MSK 106RH has an on-board current limit scheme designed to limit the output drivers anytime output current exceeds a predetermined limit. The following formula may be used to determine the value of the current limit resistance necessary to establish the desired current limit. Thermal Model: RSC= 0.7 ___ ISC Current Limit Connection Governing Equation: TJ = PD X (RθJC + RθCS + RθSA) + TA Where TJ PD RθJC RθCS RθSA TC TA TS = = = = = = = = Junction Temperature Total Power Dissipation Junction to Case Thermal Resistance Case to Heat Sink Thermal Resistance Heat Sink to Ambient Thermal Resistance Case Temperature Ambient Temperature Sink Temperature Example: In our example the amplifier application requires the output to drive a 10 volt peak sine wave across a 10 ohm load for 1 amp of output current. For a worst case analysis we will treat the 1 amp peak output current as a D.C. output current. The power supplies are ±15 VDC. See "Application Circuits" in this data sheet for additional information on current limit connections. POWER SUPPLY BYPASSING Both the negative and the positive power supplies must be effectively decoupled with a high and low frequency bypass circuit to avoid power supply induced oscillation. An effective decoupling scheme consists of a 0.1 microfarad ceramic capacitor in parallel with a 4.7 microfarad tantalum capacitor from each power supply pin to ground. It is also a good practice with high power op-amps, such as the MSK 106RH, to place a 30-50 microfarad capacitor with a low effective series resistance, in parallel with the other two power supply decoupling capacitors. This capacitor will eliminate any peak output voltage clipping which may occur due to poor power supply load regulation. All power supply decoupling capacitors should be placed as close to the package power supply pins as possible. 1.) Find Power Dissipation PD=[(quiescent current) X (+VCC - (VCC))] + [(VS - VO) X IOUT] =(3.5 mA) X (30V) + (5V) X (1A) =0.1W + 6W =6.1W 2.) For conservative design, set TJ = +125°C. 3.) For this example, worst case TA = +25°C. 4.) RθJC = 6.0°C/W 5.) Rearrange governing equation to solve for RθSA: RθSA =(TJ - TA) / PD - (RθJC) - (RθCS) = (125°C - 25°C) / 6.1W - (6.0°C/W) - (0.15°C/W) = 10.2°C/W The heat sink in this example must have a thermal resistance of no more than 10.2°C/W to maintain a junction temperature of less than +125°C. 3 Rev.
