MLX90313 Programmable IR Sensor Interface Features and Benefits Dual low noise, low offset, fully programmable amplifier chain 12 bit on-chip ADC Powerful signal conditioning and linearisation unit Multiple output options: 12 bit digital through SPI, 8 bit resolution analog linear signal outputs or 10 bit PWM, both for ambient and object temperature. On-chip programmable digital moving average LPF for ultimate low noise performance ISP I/O-configuration and analog settings, accessible by SPI serial interface. Wide supply voltage range from 4.5V-80V Applications Thermopile + thermistor amplification chain Digital or analog, linear, ambient-compensated IR sensor interface General purpose programmable sensor amplifier/ signal conditioner Ordering Information Part No. MLX90313 Temperature Suffix K Package DF Temperature Range -40C to 125C Automotive Functional Diagram Description The MLX90313 is a versatile in-circuit programmable interface, which performs signal conditioning, linearisation and ambient temperature compensation, particularly for infrared sensors combined with a thermistor. Other types of sensors can also be used in various configurations. Sensors that can be used include pressure sensors, strain gauges, acceleration sensors etc. The amplifier chains in MLX90313 are programmable in very broad ranges of gain. Both chains consist of high performance, chopper-stabilized amplifiers, providing excellent noise performance and low offset. The I/O configuration as well...
