Analog Devices Inc. AD7400AYRWZ-RL Isolated Sigma-Delta Modulator

The AD7400AYRWZ-RL from Analog Devices Inc. is a high-performance, second-order, isolated sigma-delta modulator that converts an analog input signal into a high-speed, single-bit data stream. This cutting-edge component is designed with the latest isolation technology to provide robust and reliable signal isolation, which is vital for industrial applications where precise data conversion and isolation are critical.

Featuring a wide analog input range and a high oversampling ratio, the AD7400AYRWZ-RL ensures excellent noise performance and effective resolution, making it an ideal choice for applications such as motor control, battery monitoring, and data acquisition systems where accuracy is paramount. The modulator operates over a wide temperature range, ensuring reliable performance in harsh environments.

The AD7400AYRWZ-RL incorporates iCoupler® technology, which enables it to provide galvanic isolation between the input signal and the output data stream. This isolation helps protect sensitive digital circuits from high-voltage transients and reduces the risk of ground loops, thus improving safety and system reliability. The device is capable of up to 5 kV RMS isolated voltage, which is a testament to its robustness in electrically noisy environments.

With a serial peripheral interface (SPI) compatible serial interface, the AD7400AYRWZ-RL is easy to integrate into a variety of digital systems. The device is available in a compact, 16-lead wide-body SOIC package with increased creepage and clearance to meet safety standards. The "RL" suffix indicates that this product is available in reel packaging, making it suitable for automated assembly processes.
