Description
STEVAL-ISQ007V1
This demonstration board is specifically designed
for the TSC101 integrated circuit.
The TSC101 measures a very small voltage drop
on a high-side shunt resistor, and, using an
internally fixed gain, amplifies the difference into a
ground-referenced output voltage; the
amplification gain is internally fixed.
Input common-mode and power supply voltages
are independent.
The common-mode voltage can range from 2.8 V
to 30 V in operating conditions, and up to 60 V in
absolute maximum ratings.
The supply voltage can range from 4 V to 24 V.
Current consumption of less than 300 µA over the
temperature range and low input bias current
(less than 8 µA in standard conditions, a few 100
nA if VCC isn't supplied) are particularly
interesting to save power in the application.
