Precision current sense for tight spaces
It measures current across a shunt resistor with a maximum input offset voltage of 3 µV, which keeps the measurement error small even at low shunt drops. The supply current sits at 48 µA, making it a fit for battery-powered or loop-powered monitors where every microamp counts.
The gain-bandwidth product of 33 kHz sets the usable signal bandwidth. For DC current monitoring (battery charge/discharge, motor winding current, solenoid hold) this is plenty — the amplifier settles fast enough for a few-kHz PWM switching edge. It is not a part for high-frequency AC current sensing or fast overcurrent detection below a few tens of microseconds. The 0.3 V/µs slew rate matches the bandwidth; expect a clean step response on shunt voltages that change at moderate rates.
