The LMP91200EVAL/NOPB is an evaluation platform for LMP91200, a configurable sensor AFE for use in low power analytical sensing applications. The LMP91200 is designed for two electrode sensors. This device provides all of the functionality needed to detect changes based on a delta voltage at the sensor. Optimized for low power applications. 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. The common mode output pin provides a common mode offset, which can be programmed to different values to accommodate pH sensor output ranges. Two guard pins provide support for high parasitic impedance wiring. Support for an external Pt1000, Pt100, or similar temperature sensor is integrated in the LMP91200. The control of this feature is available through the SPI interface.
