ISL28005FH-20EVAL1Z开发板套件编程器的评估板-运算放大器规格书PDF中文资料

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 50µA 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.
