Continuous operation at or above absolute maximum ratings may adversely affect the device performance and/or life cycle.
Pre and post irradiation limits at 25°C, up to 100 Krad(Si) TID (Condition A) and 50 Krad(Si) TID (Condition D), are identical unless otherwise
specified.

APPLICATION NOTES
PIN FUNCTIONS
DEVICE ASSEMBLY
-IN - The -IN pin is the negative input terminal of the sense
amplifier. Voltages as high as 44V can be applied to the pin,
relative to the negative supply pin V-.
Due to the bond pad size, this device is manufactured with gold
wirebonds.
For high voltage applications, the MSK197RH can be used
with external MOSFETs. The MOSFETs protect the device from
the full potential of the high voltage supply. The high voltage
supply is the positive rail of the device, and the Zener voltage
minus the VGS(on) potential of Q2 determines the negative
voltage rail for the device; (V-)=(V+)-(VZ-VGS). The device can
+IN - The +IN pin is the positive input terminal of the sense
amplifier. Voltages as high as 44V can be applied to the pin,
relative to the negative supply pin V-.
V+ - The V+ pin is the positive power supply for the device.
Operational currents are sourced from this pin independent of the safely sense current from 0.3V below the negative rail up to 44V
voltages on the -IN and +IN pins.
above it independent of high voltage supply, and deliver a ground
referenced signal via Q1. The values in the application circuit are
provided for reference. They may need to be adjusted based on
specific application requirements.
VOUT - The VOUT pin is the output of the amplifier. The voltage
at the output is a function of both the input differential (VSENSE±
VOS), and the voltage gain ROUT/RIN1, for RIN1= RIN2. (See
typical application ckt for more detail)
HIGH VOLTAGE SIMPLE CURRENT MONITOR
VOUT=ROUT/RIN x (VSENSE± VOS)
Set RIN1=RIN2 for best accuracy
SENSE RESISTOR
Choose a RSENSE resistor value just large enough to cover the
application dynamic range to minimize power dissipation losses.
The low 100µV typical offset voltage helps to maintain high
resolution while minimizing power dissipation.
Kelvin connection of the input resistors to the sense resistor is
recommended to minimize error in high current applications.

RADIATION TEST PERFORMANCE
Radiation performance curves have been generated for all
radiation testing performed by MS Kennedy. These curves show
performance trends throughout each test process and is located
in the MSK197RH radiation test report. The complete radiation test
report is available in the RAD HARD PRODUCTS section on the
MSK website.
