3 Description
The LMP91002 device is a programmable Analog
Front End (AFE) for use in micro-power electrochemical-sensing applications. It provides a
complete signal path solution between a not biased
gas sensor and a microcontroller generating an
output voltage proportional to the cell current.
The LMP91002’s programmability enables it support
not biased electro-chemical gas sensor with a single
design. The LMP91002 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 LMP91002’s
transimpedance amplifier (TIA) gain is programmable
through the I2C interface. The I2C interface can also be used for sensor diagnostics. The LMP91002 is
optimized for micro-power applications and operates
over a voltage range of 2.7 V to 3.6 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.
