Allegro MicroSystems CTD455 Evaluation Board
Allegro MicroSystems CTD455 Evaluation Board demonstrates the advantages of the CT455 high dV/dt optimized XtremeSense™ TMR coreless current sensor. This evaluation board supports a ±6mT magnetic field range where the CT455 sensor detects and converts the magnetic field into a linear analog output voltage. The CTD455 evaluation board attains a total error output of less than ±1% over supply voltage and temperature after calibration. While the sensor is preprogrammed to compensate for gain and offset temperature drift, the capability to adjust offset and gain soothes mechanical tolerances during sensor mounting. The CTD455 evaluation board offers less than 300ns output response time, while the current consumption is approximately 6mA. This evaluation board operates within the 4.75V to 5.50V input voltage range and –40°C to 125°C input temperature range.
