Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
Integral nonlinearity is defi ned 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 6:
Offset error is the offset voltage measured from –0.5 LSB when N
ote 2:
All voltage values are with respect to ground with GND and OGND the output code fl ickers between 0000 0000 0000 and 1111 1111 1111. wired together (unless otherwise noted).
Note 7:
Guaranteed by design, not subject to test.
Note 3:
When these pin voltages are taken below GND or above VDD, they
Note 8:
VDD = 3V, fSAMPLE = 125MHz, input range = 1VP-P with differential will be clamped by internal diodes. This product can handle input currents drive. The supply current and power dissipation are the sum total for both of greater than 100mA below GND or above VDD without latchup. channels with both channels active.
