ELECTRICAL CHARACTERISTICS
Note 13:
The common mode rejection ratios of the LTC1967 are measured
with DC inputs from 50mV to 350mV. The input CMRR is defined as the
change in V
IOS
measured between input levels of 0V to 350mV and input
levels of V
+
– 350mV to V
+
divided by V
+
– 350mV. The output CMRR is
defined as the change in V
OOS
measured with OUT RTN = 0V and OUT RTN
= V
+
– 350mV divided by V
+
– 350mV.
Note 14:
The LTC1967 input and output voltage swings are limited by
internal clipping. However, its
Σ
topology is relatively tolerant of
momentary internal clipping.

Note 15:
The LTC1967 exploits oversampling and noise shaping to reduce
the quantization noise of internal 1-bit analog-to-digital conversions. At
higher input frequencies, increasingly large portions of this noise are
aliased down to DC. Because the noise is shifted in frequency, it becomes
a low frequency rumble and is only filtered at the expense of increasingly
long settling times. The LTC1967 is inherently wideband, but the output
accuracy is degraded by this aliased noise.
