Product Identity: Part Number: LMP91000SD Manufacturer: Texas Instruments Canonical Name: LMP91000SD Configurable AFE Potentiostat Product Type: Analog Front End (AFE) Series: LMP91000 Category: Uncategorized Subcategory: Signal Conditioning Summary: The Texas Instruments LMP91000SD is a programmable analog front-end (AFE) designed for low-power electrochemical sensing applications. It provides a complete signal path between a sensor and a microcontroller. Description: The LMP91000SD from Texas Instruments is a versatile analog front-end (AFE) potentiostat designed for micro-power electrochemical sensing applications. It offers a complete signal path solution, interfacing directly between a chemical sensor and a microcontroller to generate an output voltage proportional to the cell current. This AFE supports a wide range of electrochemical sensors, including 3-lead toxic gas sensors and 2-lead galvanic cell sensors, enabling a single design to accommodate multiple sensor types. Key features include programmable cell bias voltage, low-bias voltage drift, and a programmable transimpedance amplifier (TIA) gain ranging from 2.75 kΩ to 350 kΩ. The device operates over a supply voltage range of 2.7 V to 5.25 V and features a low average supply current of less than 10 µA. The LMP91000SD communicates via a serial I2C interface, which is also utilized for sensor diagnostics. It operates within an ambient temperature range of -40°C to 85°C and is housed in a compact 14-pin WSON package. This device is suitable for applications requiring precise current measurement and signal conditioning for electrochemical cells, such as environmental monitoring, industrial process control, and portable analytical instruments.
