Micropower, Rail-to-Rail Input Current Sense Amplifier
with Voltage Output
ISL28005
The ISL28005 is a micropower, uni-directional high-side and
low-side current sense amplifier featuring a proprietary rail-to-rail
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 50A 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 -40°C to
+125°C.
