- Analog sine cosine output
- High speed, capable of measuring from 0-50k RPM
Evaluation boards for MLX90381 - EVB90381
Product description
The EVB90381 contains a single MLX90381 IC mounted in the middle of a 30.5mm x 32.4mm PCB.
These boards include mounting holes for installation into a system and a series of holes on a standard 2.54mm (0.100”) pitch allowing for connection to the MLX90381 via flying leads or a pin header.
The necessary passive components are included to allow for interfacing via two analog output signals; sine and cosine.
