Micropower, Rail to Rail Input Current Sense Amplifier
with Voltage Output
ISL28006
The ISL28006 is a micropower, uni-directional
high-side and low-side current sense amplifier
featuring a proprietary rail-to-rail input current sensing
amplifier. The ISL28006 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 ISL28006 consumes only 50µA of supply
current when operating from a 2.7V to 28V supply.
The ISL28006 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 ISL28006 is available in fixed (100V/V, 50V/V, 20V/V
and Adjustable) gains in the space saving 5 Ld SOT-23
package and the 6 Ld SOT-23 package for the adjustable
gain part. The parts operate over the extended
temperature range from -40°C to +125°C.
