1.

3.
The Power-down current is measured with all output pins disconnected; XTAL2 not connected;
EA = Port 0 = EW = V
DD
; RST = STADC = XTAL1 = V
SS
.
4.
Capacitive loading on Ports 0 and 2 may cause spurious noise pulses to be superimposed on the low level output
voltage of ALE and Ports 1, 3 and 4. The noise is due to external bus capacitance discharging into the Port 0 and
Port 2 pins when these pins make HIGH-to-LOW transitions during bus operations. In the most adverse condition
(capacitive loading
>
100 pF), the noise pulse on the ALE line may exceed 0.8 V. In such events it may be required
to qualify ALE with a Schmitt trigger, or use an address latch with a Schmitt trigger strobe input.
5.
Capacitive loading on Ports 0 and 2 may cause the high level output voltage on ALE and PSEN to momentarily fall
below to 0.9V

= 5.12 V; V
REF
= 0 V; V
DDA
= 5.0 V.
7.
The differential non-linearity (DL
e
) is the difference between the actual step width and the ideal step width.
8.
The integral non-linearity (IL
e
) is the peak difference between the centre of the steps of the actual and the ideal
transfer curve after appropriate adjustment of gain and offset error.
9.
The gain error (G
e
) is the relative difference in percent between the straight line fitting the actual transfer curve after
removing offset error, and the straight line which fits the ideal transfer curve. Gain error is constant at every point on
the transfer curve.
10. The offset error (OS
e
) is the absolute difference between the straight line which fits the actual transfer curve after
removing gain error, and a straight line which fits the ideal transfer curve. The offset error is constant at every point
of the actual transfer curve.
