The LMP91000SDX/NOPB from Texas Instruments is a programmable analog front-end (AFE) designed for micro-power electrochemical sensing applications. It provides a complete signal path between a sensor and a microcontroller, generating an output voltage proportional to the cell current.
This device supports multiple electrochemical sensors, including 3-lead toxic gas sensors and 2-lead galvanic cell sensors, with a single design. It offers programmable cell bias voltage and transimpedance amplifier (TIA) gain, adjustable from 2.75 kΩ to 350 kΩ, controllable via an I2C interface. The operating supply voltage ranges from 2.7V to 5.25V, with a low average supply current of less than 10 µA.
The LMP91000SDX/NOPB operates within an ambient temperature range of -40°C to 85°C. It is housed in a 14-pin WSON package, suitable for surface mounting. The I2C interface also facilitates sensor diagnostics.
Key features include a temperature sensor and a transimpedance amplifier. The device supports gas sensitivities from 0.5 nA/ppm to 9500 nA/ppm and allows for current range conversions from 5 µA to 750 µA full scale.
