AD8411AWBRMZ-RL

AD8411AWBRMZ-RL is a high-voltage, high-bandwidth current-sense amplifier. The buffered output voltage directly interfaces with any typical converter. This performs bidirectional current measurements across a shunt resistor in various industrial and automotive applications. The device includes circuitry to achieve a wide input common-mode range and balanced input bias currents, regardless of input differential voltage or common-mode voltage, and circuitry to achieve ultra-low CMRR drift. The device also includes circuitry to enable output accuracy in the presence of pulse-width modulation (PWM) type input common mode voltages. Applications include in-phase or High-side current sensing in, BLDC motors, Low-inductance motors, bidirectional 48 V to 12 V DC-DC converters, solenoid controls, power rail monitoring and low-side current sensing.
