Overview
The AD7400AYRWZ-RL is a specialized analog-to-digital converter (ADC) produced by Analog Devices Inc. It is a second-order, Σ-Δ (sigma-delta) modulator designed to convert an analog input signal into a high-speed, 1-bit data stream. This component features on-chip digital isolation using Analog Devices' iCoupler technology, which provides superior performance compared to traditional optocoupler devices. The AD7400AYRWZ-RL operates from a 4.5V to 5.5V power supply and is housed in a 16-lead SOIC package, making it suitable for various industrial and automotive applications where high isolation and precision are required.
