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 a 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 6. Note that if the
CONVST
pulsewidth is greater than 5.2
μ
s, the effective conversion time will increase beyond 10
μ
s.

Performance measured through full channel (multiplexer, SHA and ADC).

For best dynamic performance of the AD7863, ATE device testing has to be performed with power supply decoupling in place. In the AD7863 power-down mode of
operation, the leakage current associated with these decoupling capacitors is greater than that of the AD7863 supply current. Therefore the 40 nA typical figure shown
is a characterized and guaranteed by design figure, which reflects the supply current of the AD7863 without decoupling in place. The max figure shown in the Conditions/
Comments column reflects the AD7863 with supply decoupling in place—0.1
