LMP91000
LMP91000 Configurable AFE Potentiostat
The LMP91000 is a programmable Analog Front End ( AFE) for use in micro-power electrochemical sensing applications that 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. The LMP91000 supports gas sensitivities over a range of 0.5 nA/ppm to 9500 nA/ppm and also allows for an easy conversion of current ranges from 5µA to 750µA full scale. Its adjustable cell bias and transimpedance amplifier ( TIA ) gain are programmable through the I 2 C interface. The LMP91000 is optimized for micro-power applications and operates over a voltage range of 2.7V to 5.25V.
