Note 1:
The typical junction-to-ambient thermal resistance (
i
JA
) of the 14 pin N package is 160
§
C/W, and 82
§
C/W for the M package.
Note 2:
The accuracy of the Q value is a function of the center frequency (f
o
). This is illustrated in the curves under the heading ‘‘Typical Performance
Characteristics’’.
Note 3:
V
os1
, V
os2
, and V
os3
refer to the internal offsets as discussed in the Application Information section 3.4.
Note 4:
For
g
5V supplies the dynamic range is referenced to 2.82V rms (4V peak) where the wideband noise over a 20 kHz bandwidth is typically 200
m
V rms for
the MF5 with a 50:1 CLK ratio and 280
m
V rms for the MF5 with a 100:1 CLK ratio.
Note 5:
The short circuit source current is measured by forcing the output that is being tested to its maximum positive voltage swing and then shorting that output to
the negative supply. The short circuit sink current is measured by forcing the output that is being tested to its maximum negative voltage swing and then shorting
that output to the positive supply. These are the worst case conditions.
Note 6:
Typicals are at 25
§
C and represent most likely parametric norm.
Note 7:
Guaranteed and 100% tested.
Note 8:
Guaranteed, but not 100% tested. These limits are not used to calculate outgoing quality levels.
