New Analog Front End devices from Nisshinbo
Summary
These cutting-edge devices are designed to meet the stringent demands of modern sensor applications, offering exceptional accuracy and performance in analogue signal processing. The NA2202, NA2203, and NA2204 are 5V CMOS-based AFE ICs that incorporate a high-gain Programmable Gain Amplifier (PGA) and a 16, 20, or 24-bit Delta-Sigma (ΔΣ) Analog-to-Digital Converter (ADC). This powerful combination delivers outstanding signal accuracy and resolution, making these ICs ideal for a wide range of industrial and consumer applications, including pressure sensors, flowmeters, and thermostats. The devices are capable of handling negative voltage power supplies, allowing them to process signals close to 0V without interference from GND noise. These AFE ICs are available in a compact QFN4040-24-NB package, measuring just 4.0 × 4.0 × 0.7 mm, making them ideal for applications where space is limited.
