Current Sensors feature isolation voltage up to 2,100 Vrms.
January 3, 2007 -
Bidirectional ACS712 and unidirectional ACS713 hall-effect current sensors feature integrated shield that attenuates high dv/dt transients across leadframe. Filter pin addresses output noise and low current accuracy without attenuation effects of external RC filter. Suited for motor control applications, devices are offered in SOIC8 package.

Allegro Announces New Low Noise 2100 Vrms Hall-Effect Current Sensors
Worcester, MA, December 18, 2006 - Allegro introduces two new high performance low noise 2100Vrms isolation current sensors. Allegro's new current sensors, ACS712 (bidirectional) and ACS713 (unidirectional), provide 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 this solution ideal for motor control and high side current sense applications.
The response time of these sensors has improved by over two times of previous devices making it suitable for protection and 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.
Targeted at the consumer and industrial markets, both sensors are offered in Allegro's SOIC8 package and have an 8-10 week lead-time to market. Both the ACS712 and ACS713 are priced at $1.29 in quantities of 1,000.
