Output Drive
Pin 7 and Pin 8 can drive a 1k
or 300pF load connected
to AC ground with a
±
0.5V signal (corresponding to a
2V
P-P
differential signal). For differential loads (loads
connected from Pin 7 to Pin 8) the outputs can produce
a 2V
P-P
differential signal across 2k
or 150pF. For
smaller signal amplitudes the outputs can drive corre-
spondingly larger loads.

Noise
The wideband noise of the filter is the RMS value of the
device’s output noise spectral density. The wideband
noise data is used to determine the operating signal-to-
noise at a given distortion level. Most of the noise is
concentrated in the filter passband and cannot be removed
with post filtering (Table 1). Table 2 lists the typical change
in wideband noise with supply voltage.
Dimensions in inches (millimeters) unless otherwise noted.

DC Offset
The output DC offset of the LTC1565-31 is trimmed to less
than
±
5mV. The trimming is done with V
S
=
±
2.5V. The
output DC offset will typically change by
±
1mV when the
power supply varies from 5V to
±
5V.
