Overview
The AD7403-8BRIZ is a high-performance, second-order, Σ-Δ (Sigma-Delta) modulator produced by Analog Devices Inc. This device is designed to convert analog input signals 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 is housed in an 8-lead, wide-body SOIC package and operates over a temperature range of −40°C to +105°C. It is particularly useful in environments where high common-mode transient immunity and low EMI are crucial.
