DESCRIPTION:
The MSK 198RH is a radiation hardened dual operational amplifier for use in space and severe military applications.
This device offers rail-to-rail input and output, 10MHz gain-bandwidth product and 6V/uS slew rate. With a wide supply
range of 4.5V to ±15V and drive current to 30mA, these op amps remain stable while driving capacitve loads up to
10,000pF. The MSK 198RH is an ideal solution when multiple robust precision amplifiers are required and board space is
at a premium. The hermetically sealed MSK 198RH is offered in a 10 pin ceramic flat pack with straight or gull wing lead
form and a leadless ceramic chip carrier package for meeting most surface mount applications.

APPLICATION NOTES
4th ORDER BUTTERWORTH FILTER
SINGLE TO DIFFERENTIAL ADC DRIVER
The wide bandwidth of the MSK 198RH is ideal for designing multi-
order filter circuits. The circuit in Figure 3 shows a design that cas-
cades two 2nd order filters as a 100KHz 4th order low pass filter.
The design operates from a single supply. The filter offers a good
compromise for low parts count and performance with minimal over-
shoot and ringing characteristics that a Butterworth filter offers.
The circuit shown in Figure 1 utilizes the MSK 198RH to buffer and
convert a single analog signal into an ADC with differential inputs.
Some ADC's require an op amp to provide the appropriate gain and
offset to match the signal to the input range of the ADC. An ADC may
generate transient currents at their input due to the internal conver-
sion circuit, and these currents need to be isolated from the signal
source. The circuit in Figure 1 will provide a low impedance drive and
absorb these currents. The first op amp offsets the input signal 1.25V
while operating in unity gain. The output of the first op amp goes into
the IN+ of the ADC and the inverting input of the second op amp. The
second op amp inverts the signal around the 1.25VDC level applied to
its non-inverting input and the output is connected to the IN- of the
ADC. Optional filtering can be added to reduce high frequency noise
from the ADC inputs if required.

PERFORMANCE
Radiation performance curves for TID testing will be generated for all
radiation testing performed by MS Kennedy. These curves show per-
formance trends throughout the TID test process and will be located
in the MSK 198RH radiation test report. The complete radiation test
report will be available in the RAD HARD PRODUCTS section on the
MSK website.

nology Corporation's® LT1498/1499 and RH1498 data sheets.

INSTRUMENTATION AMPLIFIER
DIE GLASSIVATION
A simple low cost, low power consumption instrumentation ampli-
fier can be designed with the MSK 198RH. Figure 2 shows a design
that offers sensitivity trim for offset voltage, CMRR and gain. The
circuit is configured for a differential input gain of 100.
For enhanced radiation tolerance the die has a glassivation thickness
of 4KA and is not in accordance with MIL-PRF-38535.
