General Description
The MLX90255xx linear sensor array consists of a 128 x 1 array of photodiodes, associated
charge amplifier circuitry and a pixel data-hold function that provides simultaneous integration
start and stop times for all pixels. The pixels measure 200μm (H) by 66 μm (W) and there is 8
μm spacing between pixels. Operation is simplified by internal control logic that requires
only a Serial Input (SI) pulse and a clock signal. The sensor consists of 128 photodiodes
arranged in a linear array. Light energy falling on a photodiode generates photocurrent, which is integrated by the active integration circuitry associated with that pixel. During the integration
period, a sampling capacitor connects to the output of the integrator through an analog
switch. The amount of charge accumulated at each pixel is directly proportional to the light
intensity and the integration time. The output and reset of the integrators is controlled by a
132-bit shift register and reset logic. An output cycle is initiated by clocking in a logic 1 on SI.
This causes all 132 sampling capacitors to be disconnected from their respective integrators
and starts an integrator-reset period.

MLX90255 - Linear Optical Array

Description
At the heart of the MLX90247 thermopile sensors is a silicon die with a central micromachined membrane surrounded by a bulk silicon edge. The hot junctions of the thermopile are positioned near the center of the membrane and the cold junctions are located above the bulk silicon edge. Infrared irradiation of the low thermal conductivity membrane creates a temperature difference between the membrane and the surrounding bulk silicon. The resulting thermopile voltage is a function of the temperature difference between the object and the sensor.
Measurement of the absolute temperature of the object is possible by relating the thermopile signal to the temperature of the sensor. The exact temperature of the sensor is measured by a PTC thermistor integrated in the bulk silicon edge. No supply voltage is needed for the
thermopile. The sensor and thermistor can be used independently of each other if desired, as the thermopile potential is floating.

Features and Benefits
*Solid state thermopile sensor
*On-chip thermistor for ambient temperature compensation
*High reliability and long-term stability
*Low cost, small size

Applications
*Automotive contactless temperature sensing.
*IR thermometers
*Gas analysis equipment
*Occupancy detection

EVB7122 - 27 to 930MHz Transceiver Evaluation Board Description

Description
 The MLX90210 is a discrete micromachined Pressure sensor IC suitable for pressure ranges between 0 to 1.0 Bar.
The pressure medium must be dry and non-corrosive, such as air.
The circuit is a piezoresistive bridge which is realized in silicon through a special micromachining process.
As pressure is applied to the bridge, a differential voltage change is seen across the Vout pins, while a bias voltage is applied to the Vexc pins.
The MLX90210 is a versatile pressure sensor solution which can be directly interfaced with other Melexis ICs such as the MLX90308, which provides amplification, signal conditioning as well as the bias current to supply the sensor itself.

Features and Benefits
* 0 - 1.0 Bar Range
* Differential pressure sensor
* Compact Design
* High Long Term Stability

Applications
* Medical Instrumentation (Blood Pressure)
* Consumer Appliances
* Sports Equipment
* Pressure Difference and Flow Monitoring

Description
The MLX90316 is a monolithic sensor IC featuring the Triaⓧis™ Hall technology.
Conventional planar Hall technology is only sensitive to the flux density applied orthogonally to the IC surface.
The Triaⓧis™ Hall sensor is also sensitive to the flux density applied parallel to the IC surface. This is obtained through an Integrated Magneto-Concentrator (IMC®) which is deposited on the CMOS die (as an additional back-end step).
The MLX90316 is only sensitive to the flux density coplanar with the IC surface.
This allows the MLX90316 with the correct magnetic circuit to decode the absolute rotary (angular) position from 0 to 360 Degrees.
It enables the design of novel generation of non-contacting rotary position sensors that are
frequently required for both automotive and industrial applications.
In combination with the appropriate signal processing, the magnetic flux density of a small magnet (diametral magnetization) rotating above the IC can be measured in a non-contacting way (Figure 2).
The angular information is computed from both vectorial components of the flux density (i.e. BX and BY) MLX90316 produces an output signal proportional to the decoded angle.
The output is selectable between Analog, PWM and Serial Protocol.
