描述
The ISL28130ISENSEV1Z evaluation board is designed specifically for low-side bidirectional current sensing for up to 10A of current. The evaluation board uses a 1mΩ current sense resistor that is capable of handling 4W of power dissipation. The ISL28130 low-cost micropower amplifier gains the current sensing input signal and can be used to directly drive ADC inputs.
The ISL28130 is an excellent general-purpose op amp for a range of applications and is ideal for handheld devices that operate off 2 AA or single Li-ion batteries.
