TIMING CHARACTERISTICS The l denotes the specications which apply over the full operating temperature
range, otherwise specications are at TA = 25°C. (Note 5)
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 GND with GND and OGND
shorted (unless otherwise noted).
Note 3: When these pin voltages are taken below GND or above VDD, they
will be clamped by internal diodes. This product can handle input currents
of greater than 100mA below GND or above VDD without latchup.
Note 4: When these pin voltages are taken below GND they will be
clamped by internal diodes. When these pin voltages are taken above VDD
they will not be clamped by internal diodes. This product can handle input
currents of greater than 100mA below GND without latchup.
Note 5: VDD = OVDD = 1.8V, fSAMPLE = 80MHz, LVDS outputs with internal
termination disabled, differential ENC+/ENC– = 2VP-P sine wave, input
range = 2VP-P with differential drive, unless otherwise noted.
Note 6: Integral nonlinearity is dened as the deviation of a code from a
best t straight line to the transfer curve. The deviation is measured from
the center of the quantization band.
Note 7: Offset error is the offset voltage measured from –0.5 LSB when
the output code ickers between 0000 0000 0000 0000 and 1111 1111
1111 1111 in 2’s complement output mode.
Note 8: Guaranteed by design, not subject to test.
Note 9: VDD = 1.8V, fSAMPLE = 80MHz, ENC+ = single-ended 1.8V square
wave, ENC– = 0V, input range = 2VP-P with differential drive, 5pF load on
each digital output unless otherwise noted.
Note 10: Recommended operating conditions.
