SNAS517D –NOVEMBER 2011–REVISED MARCH 2013  
LMP91050 Configurable AFE for Nondispersive Infrared (NDIR) Sensing Applications  
Check for Samples: LMP91050

FEATURES  
DESCRIPTION  
The LMP91050 is a programmable integrated Sensor  
Analog Front End (AFE) optimized for thermopile  
sensors, as typically used in NDIR applications. It  
provides a complete signal path solution between a  
sensor and microcontroller that generates an output  
voltage proportional to the thermopile voltage. The  
LMP91050's programmability enables it to support  
multiple thermopile sensors with a single design as  
opposed to the multiple discrete solutions.

Building Monitoring  
The LMP91050 features  
a programmable gain  
amplifier (PGA), “dark phase” offset cancellation, and  
an adjustable common mode generator (1.15V or  
2.59V) which increases output dynamic range. The  
PGA offers a low gain range of 167V/V to 1335V/V  
plus a high gain range of 1002V/V to 7986V/V which  
enables the user to utilize thermopiles with different  
sensitivities. The PGA is highlighted by low gain drift  
(100 ppm/°C), output offset drift (1.2mV/°C at G =  
1002 V/V), phase delay drift (500ns) and noise  
specifications (0.1 μVRMS 0.1 to 10Hz) . The offset  
cancellation circuitry compensates for the “dark  
signal” by adding an equal and opposite offset to the  
input of the second stage, thus removing the original  
offset from the output signal. This offset cancellation  
circuitry allows optimized usage of the ADC full scale  
and relaxes ADC resolution requirements.

•
•
Programmable gain 167 to 7986 V/V  
Low noise (0.1 to 10 Hz) 0.1 μVRMS  
Gain Drift 100 ppm/°C (max)  
Phase Delay Drift 500 ns (max)  
Power supply voltage range 2.7 to 5.5 V  
The LMP91050 allows extra signal filtering (high  
pass, low pass or band pass) through dedicated pins  
A0 and A1, in order to remove out of band noise. The  
user can program through the on board SPI interface.  
Available in a small form factor 10–pin package, the  
LMP91050 operates from -40 to +105°C.
