A Unique Chemical/Gas Sensor Solution

Texas Instruments offers a chemical and gas sensor solution that provides onboard processing and a configurable interface, allowing a single detector to be used for multiple sensor types. Together, the LMP91000 configurable AFE potentiostat, MSP430F2003 16-bit ultra-low power MCU, XTR117 4 mA to 20mA current loop transmitter, and BQ25504 ultra-low power boost converter offer a unique chemical/gas sensor solution.

  • Configurable AFE with integrated electrode excitation
    • One design solution fits multiple electro-chemical sensors
  • 4 mA to 20 mA current loop transmitter
    • Integrated 5 V regulator capable of providing system power
    • .05% span error
  • 16-bit MCU for configuration and communication   
    • Extremely low power extends battery life and ensures operation under 4 mA
    • Enables online or factory programmed configuration and calibration of sensor
