ELECTRICAL CHARACTERISTICS
LTC2242-10
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: All voltage values are with respect to ground with GND and OGND
wired together (unless otherwise noted).
Note 3: When these pin voltages are taken below GND or above V
will be clamped by internal diodes. This product can handle input currents
of greater than 100mA below GND or above V
Note 4: V

drive, unless otherwise noted.
Note 5: Integral nonlinearity is defi ned as the deviation of a code from
a “best straight line” fi t to the transfer curve. The deviation is measured
from the center of the quantization band.

Note 6: Offset error is the offset voltage measured from –0.5 LSB when
the output code fl ickers between 00 0000 0000 and 11 1111 1111 in 2’s

Note 10: SNR minimum and typical values are for LVDS mode. Typical
values for CMOS mode are typically 0.2dB lower.
Note 11: SFDR minimum values are for LVDS mode. Typical values are for
both LVDS and CMOS modes.
Note 12: SINAD minimum and typical values are for LVDS mode. Typical
values for CMOS mode are typically 0.2dB lower.
