Nisshinbo NJU9103 Analog Front End (AFE)
Nisshinbo NJU9103 Analog Front End (AFE) is a small-size device with up to 512 times internal Programmable Gain Amplifier (PGA). This AFE includes an internal 16-bit ΔΣ type A/D converter that can perform conversion rates ranging from 0.814ksps to 6.51ksps. The NJU9103 AFE uses a wide range of gain settings to set the optimum gain for the pressure sensor and flow sensor. This AFE can be mounted in a narrow application footprint by a small 8-pin package (SSOP8). The NJU9103 AFE is used in flowmeters, thermostats, PLCs, digital panel meters, and pressure sensors.
