Note 10:
Signal-to-Noise Ratio (SNR) is measured at 5kHz and distortion
is measured at 100kHz. These results are used to calculate Signal-to-Nosie
Plus Distortion (SINAD).
Note 11:
Guaranteed by design, not subject to test.
Note 12:
Recommended operating conditions.
Note 13:
The falling CONVST edge 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 250ns
after conversion start or after BUSY rises.
Note 14:
The acquisition time would go up to 400ns and the conversion
time would go up to 1.8
μ
s. However, the throughput time (acquisition +
conversion) is guaranteed by test to be 2
μ
s max.
Note 15:
If RD
↓
precedes CS
↓
, the output enable will be gated by CS
↓
.
Note 4:
When these pin voltages are taken below V
SS
, they will be clamped
by internal diodes. This product can handle input currents greater than
100mA below V
SS
without latchup. These pins are not clamped to V
DD
.
Note 5:
V

= 5V, V
SS
= –5V, f
SMPL
= 500kHz, and t
r
= t
f
= 5ns unless
otherwise specified.
Note 6:
Linearity, offset and full-scale specification apply for a single-
ended A
IN+
input with A
IN–
grounded.
Note 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.
Note 8:
Typical RMS noise at the code transitions.
Note 9:
Bipolar offset is the offset voltage measured from –0.5LSB when
the output code flickers between 0000 0000 0000 0000 and 1111 1111
1111 1111.
