AD7400AYRWZ

AD7400AYRWZ Description

The AD7400AYRWZ from Analog Devices Inc. is a high-performance, isolated 16-bit sigma-delta (Σ-Δ) modulator designed for precision analog-to-digital conversion in demanding industrial and automotive environments. Part of the iCoupler® series, it integrates galvanic isolation with a 10 MSPS sampling rate, enabling accurate signal acquisition in noisy or high-voltage systems. The device operates on a single supply (3V–5.5V or 4.5V–5.5V) and features a serial interface for seamless integration with microcontrollers or DSPs. Packaged in a 16-pin SOIC, it is RoHS3 compliant and rated for MSL 3 (168 hours), ensuring reliability in surface-mount applications.

AD7400AYRWZ Features

• 16-bit resolution with 10 MSPS sampling rate for high-precision data acquisition.
• iCoupler® isolation technology ensures robust noise immunity and safety in high-voltage systems (up to 5 kV RMS).
• Single-supply operation (3V–5.5V or 4.5V–5.5V) simplifies power design.
• Serial interface (SPI-compatible) for easy integration with digital systems.
• Surface-mount (SOIC-16) package with REACH and RoHS3 compliance.
• Wide temperature range and low power consumption, ideal for harsh environments.
