Description
The NJU9101 is a Low Power Analog Front End IC for use in micro-power sensing applications, especially electrochemical sensors. It provides a complete signal processing solution between sensor and micro-processor as smart-sensor module. NJU9101 has 2 channel low power operational amplifiers. These amplifiers provide potentiostat and trans-impedance-amplifiers to constitute gas sensor systems. The NJU9101 has calibration circuit by using output data of built-in high precision ADC. It is suitable for temperature variation of sensor. NJU9101 operates over voltage range of 2.4V to 3.6V. Total average current consumption can be less than 5µA.
