1. Absolute Maximum Ratings are those values beyond which
the life of a device may be impaired.
2. All voltage values are with respect to ground with DGND and
AGND wired together unless otherwise noted.
3. When these pin voltages are taken below V
they will be clamped by internal diodes. This product can handle
input currents greater than 100mA below V
without latchup.
4. When these pin voltages are taken below V
clamped by internal diodes. This product can handle input
currents greater than 100mA below V
pins are not clamped to V

7. Integral nonlinearity is defined as the deviation of a code
from a straight line passing through the actual endpoints of the
transfer curve. The deviation is measured from the center of
the quantization band.
8. Bipolar offset is the offset voltage measured from –0.5LSB
when the output code flickers between 0000 0000 0000 00 and
1111 1111 1111 11.
9. Guaranteed by design, not subject to test.
10. Recommended operating conditions.
11. The falling edge of CONVST\ starts a conversion. If
CONVST\ returns high at a critical point during the conversion
it can create small errors. For best performance ensure that
CONVST\ returns high either within 650ns after the start of the
conversion or after BUSY\ rises.
