APPLICATION NOTES
SAFE OPERATING AREA
The output stage of the MSK 130 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.
The SOA Curves below illustrate various conditions of power
dissipation.
CURRENT LIMIT
The MSK 130 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 2
and 150
.
The following equation is used to select the resistor for a given
current limit value:
Rsc = 0.6/I

INPUT PROTECTION
The MSK 130 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.
STABILITY AND COMPENSATION
Since the MSK 130 is externally compensated the bandwidth
can be optimized for any gain selection. The external compen-
sation components should be located as close to the compen-
sation 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 com-
pensation 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 effec-
tively 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 ca-
pacitor 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).
