- Adjustable Current Limit DESCRIPTION: The MSK130 is a high speed, high voltage differential amplifier designed for output currents up to ±200mA. Since the MSK130 utilizes external compensation, it exhibits wide bandwidth and greater stability over a wide gain range. High frequency, high voltage instrumentation circuits and electrostatic transducers are just a sample of the applications that the MSK130 is well suited for. The device is packaged in a 10 pin insulated ceramic SIP with holes for direct heat sink attachment.

3 8548-125 Rev. F 1/18 APPLICATION NOTES INPUT PROTECTION 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. 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: 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. POWER SUPPLIES Both the negative and 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 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). SAFE OPERATING AREA 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. 2. The junction temperature of each MOSFET should be kept below the maximum rating of 150°C.
