The LMP91000SD/NOPB from Texas Instruments is a programmable analog front-end (AFE) potentiostat optimized for micro-power electrochemical sensing. This device provides a complete signal path, interfacing between a chemical sensor and a microcontroller, generating an output voltage proportional to the cell current.
Key electrical specifications include a supply voltage range of 2.7V to 5.25V, with a low average supply current of less than 10 µA. It offers a programmable transimpedance amplifier (TIA) gain ranging from 2.75 kΩ to 350 kΩ and supports cell conditioning currents up to 10 mA. The reference electrode bias current is as low as 900 pA (max) at 85°C.
Designed for versatility, the LMP91000SD/NOPB supports multiple electrochemical sensors, such as 3-lead toxic gas sensors and 2-lead galvanic cell sensors, with a single design. It features an I2C compatible digital interface for programmability of cell bias voltage and TIA gain, as well as for sensor diagnostics. The operating temperature range is from -40°C to 85°C.
This component is housed in a compact 14-pin WSON package with a 4x4 mm footprint, suitable for surface mount applications. Its 8-bit resolution and integrated features make it a suitable choice for various low-power chemical-sensing applications.
