LMP91002 Description
The LMP91002 device is a programmable Analog Front End (AFE) for use in micro-power electrochemical-sensing applications. It provides a plete signal path solution between a not biased gas sensor and a microcontroller generating an output voltage proportional to the cell current. The LMP91002’s programmability enables it support not biased electro-chemical gas sensor with a single design.
