Note 2: For operation in ambient temperature above 25C, the device must be derated based on a 150C maximum junction temperature and a thermal resistance
of 1) 80C/W junction to ambient for the dual-in-line package, 2) 105C/W junction to ambient for the small outline package, and 3) 150C/W junction to ambient for
the TSSOP package.
Note 3: To force the DNR system into maximum bandwidth, DC ground the input to the peak detector, pin 9. A negative temperature coefficient of 0.5%/C on the
bandwidth, reduces the maximum bandwidth at increased ambient temperature or higher package dissipation. AC ground pin 9 or pin 6 to select minimum
bandwidth. To change minimum and maximum bandwidth, see Appliction Hints.
Note 4: The maximum noise reduction CCIR/ARM 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.
Note 5: The CCIR/ARM weighted noise is measured with a 40 dB gain amplifier between the DNR system and the CCIR weighting filter; it is then input referred.
Note 6: Measured using the Rhode-Schwartz psophometer.
Note 7: Pin 10 is DC forced half way between the maximum bandwidth DC level and minimum bandwidth DC level. An AC 1 kHz signal is then applied to pin 10.
Its peak-to-peak amplitude is VDC (max BW) VDC (min BW).
