aDc TiMing characTerisTics Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 10:
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 11:
Guaranteed by design, not subject to test.
Note 2:
All voltage values are with respect to GND.
Note 12:
For bipolar SoftSpan ranges 7, 6, 3, and 2, zero-scale error is
Note 3:
VDDLBYP is the output of an internal voltage regulator, and should the offset voltage measured from –0.5LSB when the output code flickers only be connected to a 2.2μF ceramic capacitor to bypass the pin to GND, between 0000 0000 0000 0000 and 1111 1111 1111 1111. Full-scale as described in the Pin Functions section. Do not connect this pin to any error for these SoftSpan ranges is the worst-case deviation of the first external circuitry. and last code transitions from ideal and includes the effect of offset
Note 4:
When these pin voltages are taken below V error. For unipolar SoftSpan ranges 5, 4, 1, and 0, zero-scale error is EE or above VCC, they will be clamped by internal diodes. This product can handle input currents the offset voltage measured from 0.5LSB when the output code flickers of up to 100mA below V between 0000 0000 0000 0000 and 0000 0000 0000 0001. Full-scale error EE or above VCC without latchup.
Note 5:
When these pin voltages are taken below GND or above V for these SoftSpan ranges is the worst-case deviation of the last code DD or OV transition from ideal and includes the effect of offset error. DD, they will be clamped by internal diodes. This product can handle currents of up to 100mA below GND or above V
Note 13:
All specifications in dB are referred to a full-scale input in the DD or OVDD without latchup. relevant SoftSpan input range, except for crosstalk, which is referred to
Note 6:
–16.5V ≤ V the crosstalk injection signal amplitude. EE ≤ 0V, 7.5V ≤ VCC ≤ 38V, 10V ≤ (VCC – VEE) ≤ 38V, V
Note 14:
Temperature coefficient is calculated by dividing the maximum DD = 5V, unless otherwise specified.
Note 7:
Recommended operating conditions. change in output voltage by the specified temperature range.
Note 8:
Exceeding these limits on any channel may corrupt conversion
Note 15:
When REFBUF is overdriven, the internal reference buffer must results on other channels. Driving an analog input above V be disabled by setting REFIN = 0V. CC on any channel up to 10mA will not affect conversion results on other channels.
Note 16:
IREFBUF varies proportionally with sample rate. Driving an analog input below VEE may corrupt conversion results on other
Note 17:
Analog input buffer supply currents from IVCC and IVEE are channels. Refer to Applications Information section for further details. reduced outside the acquisition period. Refer to nap mode in Applications Refer to Absolute Maximum Ratings section for pin voltage limits related Information section. to device reliability.
Note 18:
Parameter tested and guaranteed at OVDD = 1.71V, OVDD = 2.5V,

VCC = 15V, VEE = –15V, VDD = 5V, OVDD = 2.5V, fSMPL = 800ksps, and OVDD = 5.25V. internal reference and buffer, true bipolar input signal drive in bipolar
Note 19:
A tSCKI period of 10ns minimum allows a shift clock frequency of SoftSpan ranges, unipolar signal drive in unipolar SoftSpan ranges, unless up to 100MHz for rising edge capture. otherwise specified.
Note 20:
