Vishay Unveils Innovative Isolation Amplifiers for Precision Use
Introducing Vishay's New Isolation Amplifiers
Vishay Intertechnology, Inc. (NYSE: VSH) has launched a new series of isolation amplifiers, including the VIA0050DD, VIA0250DD, and VIA2000SD, aimed at a diverse range of applications in industries such as automotive, medical, and industrial sectors. These amplifiers promise high precision, reliability, and a compact design essential for demanding applications.
Unmatched Performance with Advanced Features
The VIA series isolation amplifiers are engineered to offer remarkable thermal stability and superior measurement accuracy. With a common-mode transient immunity (CMTI) value reaching 150 kV/?s, they ensure reliable performance even in the most challenging environments, such as those faced in heavy-duty motor applications. Users can depend on these devices for consistently accurate measurements thanks to their low gain error of ± 0.05% and a minimal gain drift of 15 ppm/°C. This means fewer calibrations over time and under varying temperatures, leading to streamlined operations.
Key Specifications of the VIA Series
These amplifiers come equipped with crucial features such as low offset error and drift, reinforced isolation, and built-in diagnostics, which facilitate precision measurements of both current and voltage. A significant advantage is the integrated common mode voltage detection, which helps to avoid failures during critical measurement tasks, making them suitable for applications where reliability is non-negotiable.
Overview of the Individual Models
The VIA0050DD is tailored for compact environments demanding low power consumption. With a minimum CMTI of 100 kV/?s, it is designed for noise-sensitive applications. The amplifier supports a low differential input voltage of ± 50 mV, making it ideal for isolated current measurements in applications like motor phase sensing and power inverters.
Expanding Capabilities with VIA0250DD
Next in the lineup is the VIA0250DD, which allows for isolated voltage and current measurements with its wider differential input voltage range of ± 250 mV. This flexibility is crucial for those designing for complex electrical systems where varying specifications are commonplace.
The Leading Option: VIA2000SD
The VIA2000SD stands out with its impressive signal-to-noise ratio and bandwidth, enabling it to support high-fidelity signal transmission. Its linear differential input voltage range of 0.02 V to 2 V equips it for precise voltage measurements in applications like bus voltage monitoring and uninterruptible power supplies (UPS).
Strengths Across Diverse Applications
These isolation amplifiers are built for versatile use in applications such as bus voltage monitoring, AC motor controls, and power inverters. By ensuring reliable measurements over high voltage potential dividers and precision shunts, they enhance operational efficiency in complex systems, including renewable energy setups and critical power infrastructures.
Availability and Future Prospects
Samples and production quantities of the VIA0050DD, VIA0250DD, and VIA2000SD are currently available, with lead times ranging from 12 to 16 weeks. This timely introduction positions Vishay Intertechnology as a pivotal player in the semiconductor market, where performance meets innovation.
