LMP91050SDEVAL evaluation board LMP91050

TI (TI) launched two configurable analog front end (AFE), providing a modular easy to use for bridging microprocessor and sensor solutions. High integration LMP91050 NDIR gas sensor AFE support a variety of thermoelectric pile of sensor, suitable for NDIR sensor, indoor CO2 monitoring, specify the ventilation control, HVAC, alcohol breath analysis, greenhouse gas monitoring and detection of Freon application.

The main characteristics and advantages of NDIR LMP91050 gas sensor AFE

1 complete gas sensing solutions: AFE highly integrated programmable gain amplifier (PGA), “dark phase” offset cancellation circuit, adjustable common mode generator and SPI interface, can simplify the system design;

2 programmable gain amplifier: support for low gain range with high gain range, can be used with different sensitivity of the thermal power reactor;

3. Excellent performance: per centigrade degree 100 ppm (max) low gain drift, per centigrade degree 1.2mV output offset drift, 500ns phase retardation, 0.1 UV RMS (0.1 to 10 Hz), low noise and – 40 degrees Celsius degrees to 105 degrees Celsius broad working temperature can provide the best performance of the system.

4 compact shape: high integration support 3 mm x 4.9 mm package size, the smaller size of the terminal products can be realized.
