Current sensors provide high accuracy, low noise

Allegro has introduced two new high-performance, low-noise 2100Vrms isolation current sensors. These new current sensors, ACS712 (bidirectional) and ACS713 (unidirectional), promise lower noise and higher accuracy than previous-generation current sensors. These sensors also include an integrated shield, which effectively attenuates high dV/dt transients across the leadframe, making these devices suitable for motor control and high side current sense applications.

The response time of these sensors has improved by over two times that of previous devices, making them suitable for protection of high-speed applications. Additionally, a filter pin has been added to further reduce output noise and improve low current accuracy without the attenuation effects of an external RC filter.
