TYPICAL PERFORMANCE CHARACTERISTICS
(LTC1867)
Note 4: When these pin voltages are taken below GND, they will be
clamped by internal diodes. This product can handle input currents of
greater than 100mA below GND without latchup. These pins are not
clamped to V
Note 5: V
V
Note 6: Linearity, offset and gain error specifi cations apply for both
unipolar and bipolar modes. The INL and DNL are tested in bipolar mode.
Note 7: Integral nonlinearity is defi ned as the deviation of a code from a
straight line passing through the actual endpoints of the transfer curve.
The deviation is measured from the center of the quantization band.

Note 8: Unipolar offset is the offset voltage measured from +1/2LSB
when the output code fl ickers between 0000 0000 0000 0000 and
0000 0000 0000 0001 for LTC1867 and between 0000 0000 0000 and
0000 0000 0001 for LTC1863. Bipolar offset is the offset voltage measured
from –1/2LSB when output code fl ickers between 0000 0000 0000 0000
and 1111 1111 1111 1111 for LTC1867, and between
