LMP91050

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.

“Dark Signal” Offset Cancellation

APPLICATIONS

•

NDIR Sensing

Demand Control Ventilation

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 μV_RMS0.1 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.

KEY SPECIFICATIONS

•

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.
