Overview
The AD7403-8BRIZ-RL, produced by Analog Devices Inc., is a high-performance, second-order, Σ-Δ (Sigma-Delta) modulator. This device is designed to convert an analog input signal into a high-speed, single-bit data stream. It features on-chip digital isolation, making it suitable for applications requiring high isolation and precision. The AD7403-8BRIZ-RL operates over a temperature range of −40°C to +105°C and is packaged in an 8-lead, wide-body SOIC (Small Outline Integrated Circuit) package, which enhances creepage and clearance for improved safety and reliability.
