NAU7802SGI
Overview
The Nuvoton NAU7802SGI is a 24-bit, 2-channel analog-to-digital converter (ADC) featuring a configurable front-end with a Programmable Gain Amplifier (PGA) and an integrated temperature sensor. Designed for precision measurements, it utilizes a sigma-delta architecture to deliver high resolution and effective precision up to 23 bits. Its integrated features and low power consumption make it suitable for various embedded applications requiring accurate analog signal acquisition.
Why Choose This Part
Engineers benefit from the NAU7802SGI's 24-bit sigma-delta architecture, providing high effective precision for demanding sensor applications. The integrated PGA with gains up to 128 allows for direct interfacing with low-level sensor signals without external amplification. Its support for both 50Hz and 60Hz rejection simplifies design in AC-powered environments, and programmable power management options enable low-power operation with a standby current of 1uA.
