ELECTRICAL CHARACTERISTICS
LTC2301/LTC2305
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.
Note 3: When these pin voltages are taken below ground or above V
they will be clamped by internal diodes. These products can handle input
currents greater than 100mA below ground or above V
Note 4: V
noted.
Note 5: 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 6: Bipolar zero error is the offset voltage measured from –0.5LSB
when the output code fl ickers between 0000 0000 0000 and 1111 1111
1111. Unipolar zero error is the offset voltage measured from 0.5LSB
when the output code fl ickers between 0000 0000 0000 and 0000 0000
0001.

Note 7: Full-scale bipolar error is the worst-case of –FS or FS untrimmed
deviation from ideal fi rst and last code transitions and includes the effect
of offset error. Unipolar full-scale error is the deviation of the last code
transition from ideal and includes the effect of offset error.
Note 8: Guaranteed by design, not subject to test.
Note 9: All specifi cations in dB are referred to a full-scale ±2.048V input
with a 2.5V reference voltage.
Note 10: Full linear bandwidth is defi ned as the full-scale input frequency
at which the SINAD degrades to 60dB or 10 bits of accuracy.
Note 11: C
Note 12: REFCOMP wakeup time is the time required for the REFCOMP pin
to settle within 0.5LSB at 12-bit resolution of its fi nal value after waking up
from sleep mode.
Note 13: High temperatures degrade operating lifetimes. Operating lifetime
is derated at temperatures greater than 105°C.
