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 ОјA over the temperature range and low input bias current (less than 8 ОјA in standard conditions, a few 100 nA if VCC isn't supplied) are particularly interesting to save power in the application.
