· Using UL94-VO recognized materials
· Low voltage directive 2006/95/EEC
· Safety IEC 61010-1
Remarks:
HMS brings an additional pin, at the output for more flexibility in applications. This pin provides access to the internal voltage reference of the ASIC which can then be fed to the reference of an A/D converter (Analog Digital). This extra pin can also receive the internal reference (from 1.5 to 2.8 V) of the DSP (Digital Signal Processor) or A/D converters commonly used in power electronics, allowing cancellation of the reference temperature drift.
HMS is non-potted.
