ON Semiconductor released the new NCS21x series of bidirectional current sense amplifiers. They include integrated, highly matched precision resistors that offer an accurate, compact system design for measuring small differential voltages. The devices are able to detect common mode voltages in the range -0,3 to 26 V, making them ideal for both high-side and low-side current sensing. The zero-drift architecture of the NCS21xR provides a low input offset voltage (as low as 35 μV) and low offset drift (as low as 0,5 μV/°C). Together with integrated gain setting components, these devices are capable of sensing smaller voltage drops across the shunt, providing a higher gain accuracy and superior temperature performance.
