Description

The AD7400AYRWZ is a high-performance, isolated Σ-Δ (sigma-delta) modulator from Analog Devices. It provides 16-bit resolution and operates with a 10 MHz external clock, delivering a 1-bit data stream for digital isolation.
Key features:
- Isolation: 5 kV RMS for 1 minute (reinforced)
- Bandwidth: Up to 78 kHz
- Low noise & high linearity
- Wide supply range: 3.0 V to 5.5 V (analog), 3.0 V to 5.5 V (digital)
- SOIC-16 package
Applications include motor control, power monitoring, and industrial sensing where galvanic isolation is critical. The AD7400AYRWZ simplifies signal chain design by combining ADC and isolation in a single chip.
For detailed specs, refer to the datasheet.
