The LMP91000SDX from Texas Instruments is a versatile analog front-end (AFE) potentiostat optimized for micro-power electrochemical sensing. This device provides a complete signal path, interfacing directly between a chemical sensor and a microcontroller, generating an output voltage that is proportional to the cell current.
Key electrical specifications include a supply voltage range of 2.7 V to 5.25 V and a low average supply current of less than 10 µA. It supports programmable TIA gain from 2.75 kΩ to 350 kΩ and offers a cell conditioning current of up to 10 mA. The reference electrode bias current is as low as 900 pA (max) at 85°C, and the output drive current is 750 µA.
Designed for flexibility, the LMP91000SDX supports multiple electrochemical sensors, such as 3-lead toxic gas sensors and 2-lead galvanic cell sensors, with a single design. It accommodates 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 adjustable cell bias and TIA gain are programmable via an I2C compatible digital interface, which also facilitates sensor diagnostics.
The component operates within an ambient temperature range of -40°C to 85°C. It is housed in a 14-pin WSON package, measuring 16 mm² (4 mm × 4 mm). This AFE is suitable for applications requiring precise current-to-voltage conversion for electrochemical measurements.
