ELECTRICAL CHARACTERISTICS Note 1:
Absolute Maximum Ratings are those values beyond which the life
Note 5:
VDD = 5V, fSAMPLE = 80MHz, differential ENC/ENC = 2VP-P 80MHz of a device may be impaired. sine wave, input range = ±1.6V differential, unless otherwise specified.
Note 2:
All voltage values are with respect to GND (unless otherwise
Note 6:
Integral nonlinearity is defined as the deviation of a code from a noted). straight line passing through the actual endpoints of the transfer curve.
Note 3:
When these pin voltages are taken below GND or above V The deviation is measured from the center of the quantization band. DD, they will be clamped by internal diodes. This product can handle input currents
Note 7:
Bipolar offset is the offset voltage measured from – 0.5 LSB of greater than 100mA below GND or above VDD without latchup. when the output code flickers between 0000 0000 0000 and
Note 4:
When these pin voltages are taken below GND, they will be 1111 1111 1111. clamped by internal diodes. This product can handle input currents of
Note 8:
Guaranteed by design, not subject to test. >100mA below GND without latchup. These pins are not clamped to VDD.
Note 9:
Recommended operating conditions.
