Description
The TSC101 measures a small differential voltage
on a high-side shunt resistor and translates it into
a ground-referenced output voltage. The gain is
internally fixed.
Wide input common-mode voltage range, low
quiescent current, and tiny SOT23 packaging
enable use in a wide variety of applications.
Input common-mode and power supply voltages
are independent. Common-mode voltage can
range from 2.8V to 30V in operating conditions
and up to 60V in absolute maximum ratings.
Current consumption lower than 300µA and wide
supply voltage range allow to connect the power
supply to either side of the current measurement
shunt with minimal error.
