Typical parameters are representative of actual device performance but are for reference only. Maximum supply voltage should be derated 0.625V/°C below 25°C case temperature. Above 65°C derate linearly to 120V total at 125°C, see SOA. Internal solder reflow temperature is 180°C, do not exceed. 5 2 8548-125 Rev. F 1/18 APPLICATION NOTES SAFE OPERATING AREA INPUT PROTECTION The output stage of the MSK130 is fabricated using state of the art complimentary MOSFETs and is free from secondary breakdown limitations. There are two distinct limitations for the output stage: 1. The internal wire bonds and the geometry of the MOSFET have a maximum peak current capability of ±300mA. The MSK130 can safely handle up to ±25V of differential input voltages. In applications where this may be violated, external protection is required. Four diodes can be used as shown in the typical connection diagram. If leakage current is of concern, use JFETs connected as diodes instead. JFETs will also yield very low capacitance for high speed applications. 2. The junction temperature of each MOSFET should be kept below the maximum rating of 150°C. CURRENT LIMIT The MSK130 has an internal active current limit circuit that can be programmed with a single external resistor Rsc. The value of this resistor should be kept between 2Ω and 150Ω. The following equation is used to select the resistor for a given current limit value: The SOA Curves below illustrate various conditions of power dissipation. Rsc = 0.6/ILIMIT (See Typical Connection Diagram) TYPICAL CONNECTION DIAGRAM STABILITY AND COMPENSATION Since the MSK130 is externally compensated the bandwidth can be optimized for any gain selection. The external compensation components should be located as close to the compensation pins as possible to avoid unwanted oscillations. The capacitor Cc should be rated for the full supply voltage. Use a high quality dielectric such as NPO to maintain a desired compensation over the full operating temperature. Refer to the typical performance curves for a guide to select the desired compensation. Refer to the typical connection diagram for the location of the Rc and Cc components.

An effective decoupling scheme consists of a 0.1 microfarad ceramic capacitor in parallel with a 4.7 microfarad tantalum capacitor for each power supply pin to ground. All power supply decoupling capacitors should be placed as close to the package power supply pins as possible (pins 5 and 6). 8548-125 Rev. F 1/18 TYPICAL PERFORMANCE CURVES 4 8548-125 Rev.
