CT456 High dV/dt Optimized XtremeSense® TMR Differential, Coreless Current Sensor with Programmable Gain
■The CT456 is a high bandwidth and low noise integrated zero-loss contactless current sensor that uses Crocus Technology’s patented XtremeSense TMR technology to enable high accuracy current measurements for many consumer, enterprise, and industrial applications. It supports six (6) field ranges where the CT456 senses and translates the magnetic field into a linear analog output voltage. It achieves a total error output of less than 1.0% over voltage and temperature.
■This coreless current sensor is not only small in size and simple to design, but it also provides effective common mode rejection of more than -50 dB. This enables the CT456 to have greater than 90% immunity to stray magnetic fields thus having almost no impact on the accuracy of the current measurement.
■It has less than 300 ns output response time while the current consumption is about 6.0 mA. The CT456 is equipped with a filter function to reduce the noise on the output pin.
■The CT456 is assembled in an industry standard 8-lead SOIC package and a very low profile, 8-lead TSSOP package that are both “green” and RoHS compliant.
