Core Insights - Vishay Intertechnology, Inc. has launched a new series of isolation amplifiers, the VIA0050DD, VIA0250DD, and VIA2000SD, aimed at enhancing performance in industrial, automotive, and medical applications [1][2]. Product Features - The VIA series offers a common-mode transient immunity (CMTI) of 150 kV/μs, ensuring robust performance in harsh environments [2]. - These amplifiers exhibit a low gain error of ± 0.05% and minimal gain drift of 15 ppm/°C, allowing for calibration-free, precise measurements over time and temperature [2]. - A bandwidth of 400 kHz is provided, enabling faster measurements compared to traditional opto-based isolation amplifiers [2]. Specific Models - The VIA0050DD is optimized for space-constrained environments, featuring a minimum CMTI of 100 kV/μs and a low differential input voltage of ± 50 mV, suitable for applications like power inverters and battery energy storage systems [4]. - The VIA0250DD allows for isolated current and voltage measurements with a wider differential input voltage of ± 250 mV [4]. - The VIA2000SD offers the highest signal-to-noise ratio (SNR) and bandwidth, making it ideal for high-fidelity signal transmission in complex environments [5]. Applications - The VIA series is designed for various applications, including bus voltage monitoring, AC motor controls, power and solar inverters, and uninterruptible power supplies (UPS) [6]. - These amplifiers ensure accurate measurements across high voltage potential dividers and precision shunts, facilitating monitoring of industrial motor drives and maintaining signal integrity in critical power systems [6]. Availability - Samples and production quantities of the VIA series amplifiers are currently available, with lead times ranging from 12 to 16 weeks [7].
