Note 1

For operation in ambient temperature above 25 C the device must be derated based on a 150 C maximum junction temperature and a thermal resistance

junction to ambient as follows LM832N

90 cw LM832M-115 cw

Note 2

To force the DNR system into maximum bandwidth connect a 2k resistor from pin 9 to GND AC ground pin 9 or pin 6 to select minimum bandwidth To

change minimum and maximum bandwidth see Application Hints

Note 3

The maximum noise reduction CCIRARM weighted is about 14 dB This is accomplished by changing the bandwidth from maximum to minimum In actual

operation minimum bandwidth is not selected a nominal minimum bandwidth of about 2 kHz gives 10 dB of noise reduction See Application Hints
