The LMP91002SDE/NOPB from Texas Instruments is a programmable Analog Front End (AFE) optimized for micro-power electrochemical sensing. This device provides a complete signal path between a not biased gas sensor and a microcontroller, generating an output voltage proportional to the cell current.
Key electrical specifications include an operating voltage range of 2.7 V to 3.6 V, with an average supply current consumption of less than 10 µA. It offers a programmable Transimpedance Amplifier (TIA) gain ranging from 2.75 kΩ to 350 kΩ and supports gas sensitivities from 0.5 nA/ppm to 9500 nA/ppm. The device also allows for easy conversion of current ranges from 5 µA to 750 µA full scale.
Featuring an 8-bit resolution and a single input channel, the LMP91002SDE/NOPB utilizes an I2C-compatible digital interface for programmability and sensor diagnostics. The operating temperature range is -40°C to 85°C.
Packaged in a 14-pin WSON (4x4 mm) with surface mount, this AFE is suitable for various low-power sensing applications. The device also supports cell conditioning current up to 10 mA and has a reference electrode bias current of 900-pA maximum at 85°C.
