Analog Devices, Inc. Approves Alpha Electronics RWB Series Resistors for Use with Its New AD74413R Integrated Circuit Solution
Alpha Electronics’ Bulk Metal® Foil Technology-based RWB series improves overall environmental performance and long-term stability
MALVERN, Penn., July 29, 2020 (GLOBE NEWSWIRE) -- VPG Foil Resistors, a product group of Vishay Precision Group, Inc. (NYSE:VPG) and a manufacturer of the industry’s most precise and stable precision resistors, today announced that Analog Devices has approved for use with their new AD74413R integrated circuit solution.
The AD74413R is a quad-channel software configurable input/output solution for building and process control applications. Analog Devices noted that the outstanding stability and precision of the RWB100R0AL and RWB2K000AL resistors complement the performance and the AD74413R in real world applications.
Specifically, the calls for an external 100 Ω ‘RSENSE’ resistor used to measure current output, current input, and RTD values. Analog Devices noted that the accuracy and stability of this resistor directly affect the performance of the circuit. The Alpha Electronics RWB100R0AL resistor was approved by Analog Devices for ‘RSENSE’ due to its outstanding tolerance of 0.05%, TCR of ±2 ppm/°C max. and load-life stability of ±0.005% typical (70°C, 2000 hrs., rated power).
In addition, an external current limiting resistor of 2 kΩ (ideal) is required for the SENSEH_x pin. The accuracy of this resistor directly affects the RTD specifications. Analog Devices approved the Alpha Electronics RWB2K000AL for the SENSEH_x resistor due to its tight tolerance of 0.05%, TCR of ±2 ppm/°C max. and ultra-low capacitance.
Made in Japan, the , a brand of VPG Foil Resistors, feature low TCR of ±2 ppm/°C and resistance tolerance as low as ±0.01% in three case sizes: 0603 (RWA Series), 0805 (RWB Series), and 1206 (RWC Series). Produced with Bulk Metal® Foil technology, the RWA/RWB/RWC Series devices are optimized for industrial applications that require resistors with extremely tight load-life stability of ±0.005% typical at 70°C and rated power for 2,000 hours. In these applications, the devices provide superior TCR (temperature coefficient of resistance), long-term stability and pulse handling capability when compared to thin-film resistors.
Samples and production quantities of the RWB100R0AL and RWB2K000AL are available now.
