Introduction to Sensor Measurement Analog Front End ICs (AFEs)
An analog front end (AFE) is a circuit system that converts analog signals from sensors into digital signals. It performs singal amplification, filtering and denoising to improve signal quality and precision. This contributes to improving data reliability by making digital processing at the next circuit stage done precisely.
Our AFE products feature low power consumption and high-precision signal processing, and correspond to a wide variety of sensor applications. Our proprietary technology provides high noise immunity and excellent linearity, enabling faithful reproduction of sensor signals. Also, applying small packages makes it possible to downsize mounting area, and therefore they are suitable for portable devices and IoT applications.
We Support Your Product Development
by Easy Board Design and Advanced Sensing.
1. NA2202/NA2203/NA2204, AFE Series for High-precision Measurement
Ideal for scenes that require high resolution such as temperature and flow rate.
The 5V operation is highly compatible with industrial MCU drive voltage, and 16-bit (NA2202), 20-bit (NA2203), and 24-bit (NA2204) resolutions are available.
Each product is pin-compatible, enabling reduction of development man-hours and commonization of boards.
2. NJU9101, Low Power AFE
Ideal for scenes demanding long battery life.
The NJU9101 achieves industry-leading low power consumption, enabling prolongation of battery life of battery-powered applications.
Also, the built-in digital calibration circuit for temperature variation in sensors makes it possible to output stable data.
3. NA2201, NJU9102 / NJU9102A, Digital Earth Leakage Detector ICs (Ground Fault Current Detector ICs)
For avoiding accidents caused by electric leakage.
[AC/DC Detection] NA2201
A digital earth leakage current detector IC with overvoltage detection / DC detection. The overvoltage detection function supports over voltage detection (neutral conductor open-phase protection). The delay time can be set independently for two systems, one for earth leakage detection and the other for over voltage detection.
[AC Detection] NJU9102 / NJU9102A
A digital earth leakage current detector IC. These ICs can suppress noise thanks to the built-in digital filter, compared to conventional analog circuits.
