NOTES:
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.
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.
3. When these pin voltages are taken below VSS or above VDD
,
they will be clamped by internal diodes. This product can
handle input currents greater than 100mA below VSS or above
VDD without latchup.
9. Guaranteed by design, not subject to test.
10. Recommended operating conditions.
11. The falling edge of CONVST\ starts a conversion. If CON-
VST\ 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.
4. When these pin voltages are taken below VSS, they will be
clamped by internal diodes. This product can handle input
currents greater than 100mAbelow VSS without latchup. These
pins are not clamped to VDD
.
5. VDD = 5V, VSS = –5V, fSAMPLE = 800kHz, tr = tf = 5ns unless
otherwise specified.
6. Linearity, offset and full-scale specifications apply for a
single ended +AIN input with – AIN grounded.
7. Integral nonlinearity is defined as the deviation of a code
