Allegro MicroSystemsACS70331EESATR-005U3Sensori di corrente

The Allegro Micro Systems current sensors are first integrated, high sensitivity, current sensor IC for < 5 A current sensing applications. This device operates from a single 3.3 V power supply and is qualified over the full commercial temperature range of –40°C to 85°C. It is offered in a low-profile, space-saving surface mount QFN-12 and SOIC-8 packages. This device has a minimum operating supply voltage of 3 V and a maximum of 4.5 V. In order to guarantee safe delivery and allow for quick mounting of this component after delivery, it will be enclosed in tape and reel packaging during shipment.

Features and Benefits:
• High sensitivity current sensor IC for sensing up to 5 A (DC or AC)
• 1 MHz bandwidth with response time< 550 ns
• Low noise: 8 mA(rms) at 1 MHz
• Non-ratiometric, analog output proportional to AC and DC current
• Single 3.3 V supply operation
• High DC PSRR enables use with low accuracy power supplies or batteries (3 to 4.5 V operation)
• 1.1 mO primary conductor resistance results in low power loss
• small surface mount QFN-12 and SOIC-8 packages for space-constrained applications
