• Manufacturer Part Number: MLX90609EEA-R2
• Description: Angular Rate Sensor (Standard version)
• Manufacturer: MELEXIS [Melexis Microelectronic Systems]

The MLX90609 can simultaneously output analog and digital signals.
The analog output signal can be fed to a microcontroller (µC) that contains an analog-to-digital
converter. A multiplexer can be used to select between the temperature and the angular rate
signals. The MLX90609 generates an internal reference voltage used for supplying the ADC,
thereby maintaining accuracy regardless of the supply voltage of the µC.
Whilst supplying the analog output signal, the MLX90609 can simultaneously send a digital output
signal to the µC through the SPI.
