HDG poles can be designed to encircle existing structures with ease and facilitate future expansion or retrofitting. HDG steel poles are self-conducting and thus have no need for a full-length copper grounding wire, and they can either be embedded or have an anchor base, and do not require fastener retightening due to pole shrinkage.

Analog Devices, Inc. (NASDAQ: ADI), a global leader in high-performance signal processing solutions, has launched the **AD7403**, the most accurate isolated sigma-delta modulator available in the industry, designed for precise current and voltage measurements in DC/AC power conversion applications. The **AD7403** delivers an impressive 81 dB signal-to-noise ratio (SNR) and a minimum SINAD of 78 dB at 78 KSPS under operating conditions ranging from -40°C to +125°C—performance that is 11 times better than competing devices. This enhanced SNR ensures more accurate current and voltage readings, which can significantly reduce torque ripple in motor shafts, improving overall motor drive performance. Additionally, higher SINAD values contribute to increased efficiency in power conversion systems like motor drives, solar inverters, and wind energy converters.
The **AD7403** integrates Analog Devices’ proprietary **iCoupler™** digital isolation technology, offering a single-chip solution that converts analog signals into 1-bit data streams with a maximum clock frequency of up to 20 MHz. It enables precise voltage measurement across a shunt resistor, making it ideal for high-voltage power conversion and motor drive applications. Engineers can now replace traditional Hall effect sensors—which are less accurate and more expensive—with the **AD7403**, which offers higher isolation voltages (up to 1250 V peak).
For more details, you can refer to the **AD7403** datasheet here: [http://datasheet.eepw.com.cn/datasheet/show/id/3121156](http://datasheet.eepw.com.cn/datasheet/show/id/3121156)
Thanks to its high performance, the **AD7403** allows for the use of smaller shunt resistors, reducing heat dissipation while maintaining measurement accuracy. This makes it particularly suitable for applications where thermal management is critical.
Key features of the **AD7403** include:
- External clock input range: 5 MHz to 20 MHz
- 16-bit no missing code
- Offset drift: 1.5 μV/°C (typical)
- On-chip digital isolator
- On-chip reference voltage
- True bipolar analog input range: ±320 mV
- High common-mode transient immunity: >25 kV/μs
The **AD7403** is well-suited for integration with other Analog Devices products used in motor control and power conversion systems, such as the **ADSP-CM40x** mixed-signal control processor, the **ADuM6000** isolated 5 kV DC/DC converter, and the **ADP2441** 36 V, 1 A synchronous step-down DC/DC regulator.
Whether you're designing motor drives, renewable energy systems, or industrial power solutions, the **AD7403** provides a reliable and high-performance option for accurate signal isolation and conversion.
