3 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. The LMP91000 supports
gas sensitivities over a range of 0.5 nA/ppm to 9500
nA/ppm. It also allows for an easy conversion of current ranges from 5 μA to 750 μA full scale.
The LMP91000’s adjustable cell bias and transimpedance amplifier (TIA) gain are
programmable through the I2C interface. The I2C
interface can also be used for sensor diagnostics. An
integrated temperature sensor can be read by the user through the VOUT pin and used to provide
additional signal correction in the μC or monitored to
verify temperature conditions at the sensor.
The LMP91000 is optimized for micro-power applications and operates over a voltage range of 2.7
to 5.25 V. The total current consumption can be less
than 10 μA. Further power savings are possible by
switching off the TIA amplifier and shorting the
reference electrode to the working electrode with an
internal switch.

2023-7-10LMP91000-传感器的AFE系统-配置低功耗化学传感应用的AFE电位
LMP91000:传感器的AFE系统:配置低功耗化学传感应用的AFE电位 LMP91000是一个可编程的模拟前端(AFE)在使用微功率电化学传感应用。 它提供了一个完整的传感器之间的信号路径解决方案和一个微控制器,产生一个输出电压成正比电池电流。 LMP91000的可编程使它能够支持多个电化学传感器,例如3,导致有毒气体传感器和2导致原电池传感器多个分立的解决方案,而不是一个单一的设计。 LMP91000支持气体的敏感性 0.5 NA / ppm到9500 NA / ppm的范围。它也允许一个5μA电流范围从750μA充分的轻松转换规模。
