As the world’s leading supplier of data converters, Analog Devices is constantly introducing new A/D converters (ADCs) that drive system architectures. In the motor control arena, ADI’s converters solve the challenges associated with current and voltage monitoring, optical encoder feedback, and resolver-to-digital conversion. The introduction of the isolated ADC with its 3.75 kV standoff voltage is one example of ADI’s breakthroughs in performance and integration to ease the burden of design.

Isolation Amplifiers provide power supply designers with a higher performing, single chip alternative to isolation techniques based on optocouplers and shunt regulators. Analog Devices ADuM3190 and ADuM4190 isolated error amplifiers have a 400 kHz bandwidth, with 0.5% typical initial accuracy at 25°C and 1% total accuracy over the extended temperature range of –40˚C to +125˚C. This provides manufacturers of ac-to-dc and dc-to-dc power supplies with a significant upgrade in speed and operating temperature range, as well as a 5× improvement in transient response.

Analog Devices small form factor isolated gate drivers are designed for the higher switching speeds and system size constraints required by power switch technologies such as SiC (silicon carbide) and GaN (gallium nitride), while still providing reliable control over switching characteristics for IGBT (insulated gate bipolar transistor) and MOSFET (metal oxide semiconductor field effect transistor) configurations for high-side and low-side switches. These isolated gate drivers leverage ADI’s proven iCoupler isolation technology combined with high speed CMOS and monolithic transformer technology to enable ultralow propagation delay without sacrificing common-mode transient immunity (CMTI) performance. High pulse fidelity architecture enables motor power efficiency to meet new required efficiency levels, and superior timing performance stability reduces voltage distortion, as well as harmonic and output power content on solar inverters.
