ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 7:
Full-scale bipolar error is the worst-case of –FS or FS untrimmed may cause permanent damage to the device. Exposure to any Absolute deviation from ideal fi rst and last code transitions and includes the effect Maximum Rating condition for extended periods may affect device of offset error. Unipolar full-scale error is the deviation of the last code reliability and lifetime. transition from ideal and includes the effect of offset error.
Note 2:
All voltage values are with respect to ground.
Note 8:
Guaranteed by design, not subject to test.
Note 3:
When these pin voltages are taken below ground or above VDD,
Note 9:
All specifi cations in dB are referred to a full-scale ±2.048V input they will be clamped by internal diodes. These products can handle input with a 2.5V reference voltage. currents greater than 100mA below ground or above VDD without latchup.
Note 10:
Full linear bandwidth is defi ned as the full-scale input frequency
Note 4:
VDD = 5V, fSMPL = 14kHz, internal reference unless otherwise at which the SINAD degrades to 60dB or 10 bits of accuracy. noted.
Note 11:
CB = capacitance of one bus line in pF (10pF ≤ CB ≤ 400pF)
Note 5:
Integral nonlinearity is defi ned as the deviation of a code from a
Note 12:
REFCOMP wakeup time is the time required for the REFCOMP pin straight line passing through the actual endpoints of the transfer curve. to settle within 0.5 LSB at 12-bit resolution of its fi nal value after waking The deviation is measured from the center of the quantization band. up from sleep mode.
Note 6:
Bipolar zero error is the offset voltage measured from –0.5 LSB
Note 13:
High temperatures degrade operating lifetimes. Operating lifetime when the output code fl ickers between 0000 0000 0000 and 1111 1111 is derated at temperatures greater than 105°C. 1111. Unipolar zero error is the offset voltage measured from 0.5 LSB when the output code fl ickers between 0000 0000 0000 and 0000 0000 0001. 23015fb 6
