Introduction
The Texas Instruments LMP91000EVM evaluation module (EVM) helps designers evaluate the operation and
performance of the LMP91000 Sensor Analog Front End for Electrochemical sensor. The LMP91000EVM is
part of the Sensor AFE eval platform
The EVM contains one LMP91000, (See Table 1).

The LMP91000EVM is provided with a 16 bit ADC (ADC161S626) in order to capture the output of the LMP91000.
The LMP91000EVM is not provided with any gas sensor. It supports 3-lead electrochemical cells and 2-lead
galvanic cell in potentiostat configuration.
