The AD7401YRWZ-REEL7 is a second-order sigma-delta (Σ-Δ) modulator from Analog Devices that integrates on-chip digital isolation using iCoupler technology. It converts an analog input signal into a high-speed 1-bit data stream, operating from a 5 V power supply and accepting a differential input voltage range of ±200 mV (full-scale ±320 mV). The analog input is continuously sampled by the modulator, eliminating the need for external sample-and-hold circuitry.
The device provides 16-bit resolution with no missing codes and typical integral nonlinearity (INL) of ±2 LSB. It features a maximum external clock rate of 20 MHz and a maximum offset drift of 3.5 µV/°C. The serial data interface supports both 5 V and 3 V supply voltages (VDD2). The AD7401 is designed for low power operation, drawing a maximum supply current of 20 mA at 5.25 V.
The modulator is housed in a 16-lead SOIC wide-body package (16-SOIC) and supports surface mount mounting. It operates over an industrial temperature range of -40°C to +105°C. The part includes an on-board reference and digital isolator, making it suitable for applications requiring galvanic isolation.
