Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 7:
Integral nonlinearity is defined as the deviation of a code from a may cause permanent damage to the device. Exposure to any Absolute straight line passing through the actual endpoints of the transfer curve. Maximum Rating condition for extended periods may affect device The deviation is measured from the center of the quantization band. reliability and lifetime.
Note 8:
Zero-scale error is the offset voltage measured from –0.5LSB
Note 2:
All voltage values are with respect to ground. when the output code flickers between 0000 0000 0000 0000 and

Full-scale error is the worst-case deviation of DD, V the first and last code transitions from ideal and includes the effect of DDL or OVDD, they will be clamped by internal diodes. This product can handle input currents up to 100mA below ground or above V offset error. DD, VDDL or OVDD without latchup.
Note 9:
When REFBUF is overdriven, the internal reference buffer must be

When this pin voltage is taken below ground, it will be clamped by turned off by setting REFIN = 0V. an internal diode. When this pin voltage is taken above VDDL, it is clamped
Note 10:
All specifications in dB are referred to a full-scale ±VREFBUF by a diode in series with a 2k resistor. This product can handle input differential input. currents up to 100mA below ground without latchup.
Note 11:
Temperature coefficient is calculated by dividing the maximum
Note 5:
VDD = 5V, VDDL = 2.5V, OVDD = 2.5V, fSMPL = 10MHz, change in output voltage by the specified temperature range. REFIN = 2.048V, single-ended CNV, one-lane output mode unless
