The AWN-3 is an encapsulated filter module offering A, B and C weighting
networks to Type 0 precision. The AWN-3 is designed for use in OEM
applications where a plug-in acoustic weighting network is required.
device offers simultaneous A, B and C weighted outputs with a ±
2.5V signal range that is suitable for most modern instrumentation.
Power requirement is a dual, low current ± 3.5V to ±
15V supply. On board regulation and reverse voltage protection are
stand alone and experimental applications, a development board is
available for the AWN-3 module providing convenient power supply
and signal connections.
