Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: All voltage values are with respect to ground with GND and OGND
wired together (unless otherwise noted).
Note 3: When these pin voltages are taken below GND or above V
be clamped by internal diodes. This product can handle input currents of
greater than 100mA below GND or above V
Note 4: V
LVDS outputs, differential ENC
2V
Note 5: Integral nonlinearity is defined as the deviation of a code from a “best
straight line” fit to the transfer curve. The deviation is measured from the
center of the quantization band.
