Rev 5.00
October 24, 2013 Micropower, Rail-to-Rail Input Current Sense Amplifier with Voltage Output
The ISL28005 is a micropower, uni-directional high-side and
low-side current sense amplifier featuring a proprietary rail-torail input current sensing amplifier. The ISL28005 is ideal for
high-side current sense applications where the sense voltage
is usually much higher than the amplifier supply voltage. The
device can be used to sense voltages as high as 28V when
operating from a supply voltage as low as 2.7V. The
micropower ISL28005 consumes only 50ВµA of supply current
when operating from a 2.7V to 28V supply.
The ISL28005 features a common-mode input voltage range
from 0V to 28V. The proprietary architecture extends the input
voltage sensing range down to 0V, making it an excellent
choice for low-side ground sensing applications. The benefit of
this architecture is that a high degree of total output accuracy
is maintained over the entire 0V to 28V common mode input
voltage range.
The ISL28005 is available in fixed (100V/V, 50V/V and 20V/V)
gains in the space saving 5 Ld SOT-23 package. The parts
operate over the extended temperature range from -40В°C to
+125В°C. Features Low Power Consumption .50ВµA,Typ Supply Range . .2.7V to 28V Wide Common Mode Input 0V to 28V Fixed Gain Versions …
