General Description

The LMP91000 is a programmable analog front-end (AFE) for use in micro-power electrochemical sensing applications.

It provides a complete signal path solution between a sensor and a microcontroller that generates an output voltage proportional to the cell current.

The LMP91000’s programmability enables it to support multiple electrochemical sensors such as 3-lead toxic gas sensors and 2-lead galvanic cell sensors with a single design as opposed to the multiple discrete solutions.

Key Features

  • 1 Typical Values, TA = 25°C.
  • Supply Voltage 2.7 V to 5.25 V.
  • Supply Current (Average Over Time).
