The HLSR series current transducers from LEM USA bring 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 0.5 V to 2.65 V) of the DSP (digital signal processor) or A/D converters commonly used in power electronics, allowing cancellation of the reference temperature drift.
