LMP91000 - programmable analog front-end

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.

Features

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