World's first configurable NDIR gas sensing and pH sensing AFEs?

World's first configurable NDIR gas sensing and pH sensing AFEs?

Texas Instruments has introduced two configurable analogue front ends (AFEs) designed to provide an easy to use, modular solution for bridging the gap between the microprocessor and sensor.

According to TI, design engineers can dramatically reduce development time by using a single AFE across multiple non-dispersive infrared (NDIR) gas sensor and pH sensor platforms instead of designing several complex discrete solutions.

The AFEs are designed for use with TI's WEBENCH Sensor AFE Designer software and bench top development system. The tools enable engineers to select a sensor, design and configure the solution and download configuration data to the sensor AFE for immediate prototyping.

The LMP91050 NDIR gas sensing AFE supports multiple thermopile sensors for NDIR sensing, indoor CO2 monitoring, demand control ventilation, HVAC, alcohol breath analysis, greenhouse gas monitoring and Freon detection.

The LMP91200 pH sensing AFE supports two electrode pH sensors used in analyser platforms for emissions monitoring, steam and water quality monitoring, chemical/petrochemical plants, food processing and more.

Available immediately, the LMP91050 gas sensing AFE is offered in a 10pin MSOP package and the LMP91200 pH sensing AFE is supplied in a 16pin TSSOP package.
