LMP91002SD/NOPB Description

Short technical summary and product information.

The LMP91002SD/NOPB from Texas Instruments is a configurable Analog Front End (AFE) optimized for micro-power electrochemical-sensing applications. It provides a complete signal path between a non-biased gas sensor and a microcontroller, generating an output voltage proportional to the cell current.

This device supports gas sensitivities ranging from 0.5 nA/ppm to 9500 nA/ppm and allows for current range conversions from 5 µA to 750 µA full scale. The transimpedance amplifier (TIA) gain is programmable via the I2C interface, which can also be used for sensor diagnostics.

Operating within a voltage range of 2.7 V to 3.6 V, the LMP91002SD/NOPB consumes less than 10 µA on average. It is housed in a 14-pin WSON package and operates over an ambient temperature range of -40°C to 85°C. Further power savings are achievable by switching off the TIA amplifier and shorting the reference electrode.

Key electrical specifications include a supply voltage of 2.7V to 3.6V, a low average supply current of less than 10 µA, and a programmable TIA gain from 2.75 kΩ to 350 kΩ. The device offers 1 input channel and an 8-bit resolution.
