AD7401YRWZ

AD7401YRWZ Description

The AD7401YRWZ from Analog Devices Inc. is a high-performance, 16-bit isolated 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 (up to 5 kV RMS) with a serial interface, enabling robust signal transmission across noisy or high-voltage boundaries. The device operates on a dual supply (3V–5.5V and 5V), making it versatile for mixed-voltage systems. Packaged in a 16-pin SOIC tube, it meets ROHS3 and REACH compliance, with an MSL 3 (168 hours) rating for moisture sensitivity.

AD7401YRWZ Features

• 16-Bit Resolution: Delivers high-accuracy data conversion for precision applications.
• iCoupler Isolation: Combines isolation and data transmission in a single package, eliminating external optocouplers.
• Dual-Supply Operation: Supports 3V–5.5V (primary side) and 5V (secondary side) for flexible system integration.
• Serial Interface: Simplifies communication with microcontrollers or DSPs.
• High CMTI (50 kV/µs): Ensures reliability in high-noise environments like motor drives or power inverters.
• Wide Temperature Range: Suitable for industrial (–40°C to +125°C) and automotive applications.

AD7401YRWZ Applications

• Motor Control: Isolates current/shunt measurements in inverters and servo drives.
• Power Monitoring: Accurate energy metering in smart grids or UPS systems.
• Battery Management Systems (BMS): Isolated voltage/current sensing in EVs and renewable energy storage.
• Industrial Automation: PLCs, isolated sensor interfaces, and process control.
• Medical Equipment: Patient-isolated diagnostics where safety is critical.
