The LMP91200MT/NOPB is a Sensor Analog Front End for use in low-power, analytical-sensing applications. The LMP91200 is designed for 2-electrode sensors. This device provides all of the functionality needed to detect changes based on a delta voltage at the sensor. With its extremely low input bias current it is optimized for use with pH sensors. Also, in absence of supply voltage the very low input bias current reduces degradation of the pH probe when connected to the LMP91200. Depending on the configuration, total current consumption for the device is 50µA while measuring pH.
