MLX91801 General Description
The MLX91801 is a System in a Package (SIP) combining an analog pressure sensor and a low-power sensor interface with an MLX16 micro-controller in a custom, pressure ported, plastic SO16 package. The device measures pressure, temperature and supply voltage. The pressure sensing element is a MEMS based absolute pressure sensor. The communication interface provides commands for receiving and sending data to the host system. A standard software library with low-level routines gives access to all the IC’s functions. Application examples provided by Melexis offer an introduction to the Melexis microcontroller programming and allow quick custom developments. The MLX91801 pressure sensor block offers 1% Full Scale accuracy. The default pressure range is 100 – 800 kPa. Other ranges are available by request.
