TIMING DIAGRAM
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: VDD = 3.3V, fSAMPLE = 65MHz (LTC2205), 40MHz (LTC2204)
differential ENC+/ENC= 2VP-P sine wave with 1.6V common mode,
input range = 2.25VP-P with differential drive (PGA = 0), unless otherwise
specied.
Note 5: 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 6: Offset error is the offset voltage measured from –1/2LSB when the
output code ickers between 0000 0000 0000 0000 and 1111 1111 1111
1111 in 2’s complement output mode.
Note 7: Guaranteed by design, not subject to test.
Note 8: Recommended operating conditions.
The
l denotes the specications which apply over the full operating temperature
range, otherwise specications are at TA = 25°C. (Note 4)
