Configurable AFE potentiostat for low power consumption chemical battery monitoring1 characteristic 3 description
1 • typical, Ta = 25 ° C lmp91000 is a programmable analog front end (AFE) suitable for micro
• supply voltage: 2.7V to 5.25V power consumption electrochemical sensing applications. It can provide a combination of sensors and microcontrollers
• complete signal path solution between power supply current (average value in service time) < 10 µ a, which can generate battery power
• the battery regulates the current up to 10mA flow proportional to the output voltage. The programmability of the lmp91000 enables it to
• the reference electrode bias current (85 ° C) of 900pa (maximum) is sufficient to support multiple applications through a single design as opposed to multiple discrete solutions
• output drive current 750 µ a electrochemical sensors, such as 3-wire toxic gas sensor and 2-wire toxic gas sensor
• a complete regulator circuit lead galvanic cell type sensor connected to most chemical batteries. Lmp91000 supports 0.5na/ppm to
• gas sensitivity within the range of programmable battery bias voltage 9500na / ppm. It can also achieve 5 µ a
• simple conversion of low bias voltage drift to 750 µ a full-scale current range.
• programmable transimpedance amplifier (TIA) gain 2.75k Ω to 350K Ω lmp91000 adjustable battery bias and transimpedance amplifier (TIA) boost
• filling current and pulling current can be obtained through I
2C interface programming.
The 2C interface can also be used for sensor diagnostics
1. 2Ccompatible digital interface is disconnected. The integrated temperature sensor can be read by the user through Vout pin,
• ambient operating temperature range - 40 ° C to 85 ° C and can be used to provide additional signal correction in µ C, or
• the 14 pin wafer level small profile leadless (WSON) package is monitored to verify the temperature of the sensor.
• by WEBENCH ® Sensors are supported by AFE design tools
The lmp91000 is optimized for micro power applications with low operating voltage
2. The application range is 2.7V to 5.25V. The total flow consumption is less than 10 μ A。 You can pass
• chemical composition identification, closing TIA amplifier and using an internal switch to connect the reference electrode to the instrument
• galvanometer shall be used as electrode short circuit to further save energy.
