Accurate current measurement device Allegro CT416-HSN850DR with low current consumption and immunity to common mode fields
Product Overview
The Allegro CT416 is a high-bandwidth, ultra-low noise integrated contact current sensor utilizing XtremeSense TMR technology for high-accuracy current measurements. It offers a linear analog output voltage, supporting eight current ranges up to 65 A with a total output error of approximately 1.0% full-scale. The device features a fast response time of ~300 ns, low current consumption, and immunity to common-mode fields. It is offered in an industry-standard, green, RoHS-compliant 8-lead SOIC package. This sensor is suitable for various industrial, consumer, and automotive applications including solar/power inverters, UPS, SMPS, telecom power supplies, motor control, power utility meters, and overcurrent fault protection. Note: The CT416 is classified as NOT FOR NEW DESIGN and sales are restricted to existing customer applications.
