This 10
μ
s includes the “wake-up” time from standby. This “wake-up” time is timed from the rising edge of
CONVST
, whereas conversion is timed from the falling
edge of
CONVST
, for narrow
CONVST
pulsewidth the conversion time is effectively the “wake-up” time plus conversion time, hence 10
μ
s. This can be seen from
Figure 3. Note that if the
CONVST
pulsewidth is greater than 5
μ
s, the effective conversion time will increase beyond 10
μ
s.

NOTES
1
Sample tested at +25
°
C to ensure compliance. All input signals are measured with tr = tf = 1 ns (10% to 90% of +5 V) and timed from a voltage level of +1.6 V.
2
The SCLK maximum frequency is 16 MHz. Care must be taken when interfacing to account for the data access time, t
4
, and the setup time required for the user’s
processor. These two times will determine the maximum SCLK frequency with which the user’s system can operate. See Serial Interface section for more information.
3
Measured with the load circuit of Figure 1 and defined as the time required for an output to cross 0.8 V or 2.0 V.
4
Derived from the measured time taken by the data outputs to change 0.5 V when loaded with the circuit of Figure 1. The measured number is then extrapolated back
to remove the effects of charging or discharging the 50 pF capacitor. This means that the time, t
6
, quoted in the timing characteristics is the true bus relinquish time
of the part and as such is independent of external bus loading capacitances.

*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD7894 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
WARNING!
