Allegro MicroSystems evaluation boards simplify the evaluation process for its tunnel magnetoresistance (TMR) current sensors. The boards provide test points for convenient access to device pins, allowing for quick measurement and validation without the need for complex test set-ups.Â
The CTD455-BB-48B5 board provides a simple way to evaluate the performance of the CT455 XtremeSenseâ„¢ TMR current sensor. The CT455 on the board senses and translates the magnetic field into a linear analog output voltage. The current sensor achieves a total error output of less than 1% over voltage and temperature.Â
Key features:
- Preset magnetic field range: ±6 mT or ±48 mT
- Low-noise performance
- Optimized for high dV/dt applications
- Less than 300 ns response time
- 5 V supply voltage
- Operating-temperature range: -40°C to 125°C
