Analog Devices AD7401 Product Handbook Rev D
The AD7401 from Analog Devices is a second‑order sigma‑delta modulator that converts an analog input into a high‑speed 1‑bit data stream. It features an on‑chip digital isolator, reference, and operates from a 5 V supply with a differential input range of ±200 mV.
The device is supplied in a 16‑lead SOIC package, supports a maximum external clock rate of 20 MHz, and meets safety standards such as UL 1577 with a 5000 Vrms isolation voltage. It operates over a temperature range of –40 °C to +105 °C and includes detailed pin configurations and timing specifications.
