Product List
The next few slides features the LMP91000 low-power, electrochemical Sensor AFE. It is designed to support low power electrochemical sensor applications. This is the most popular type of sensor used for toxic gas sensing. The product supports dozens of different toxic gases and hundreds of different sensors. Configurability allows it to address the critical parameters of each gas with a single IC instead of requiring multiple discrete solutions. The drawing on this slide shows the product’s configurable blocks. Blue identifies the configurable blocks associated with the sensor bias or drive. Bias can be positive or negative depending on the type of sensor. Orange identifies the configurable blocks associated with the sensor signal path. The gain of the signal path is adjustable allowing the LMP91000 to support many sensors and gas concentrations. Green identifies the configurable blocks associated with the output of the LMP91000. These include the I2C digital interface and a temperature output.
