LPC2292/2294
16/32-bit ARM microcontrollers with external memory interface
[1] Typical ratings are not guaranteed. The values listed are at room temperature (+25 C), nominal supply voltages.
[2] Internal rail.
[3] External rail.
[4] Including voltage on outputs in 3-state mode.
[5] V

supply voltages must be present.
[6] 3-state outputs go into 3-state mode when V
DD(3V3)
is grounded.
[7] Accounts for 100 mV voltage drop in all supply lines.
[8] Allowed as long as the current limit does not exceed the maximum current allowed by the device.
[9] Minimum condition for V

= 4.5 V, maximum condition for V
I
=5.5V.
[10] Applies to P1[25:16].

[1] Conditions: V
SSA
=0V, V
DDA
=3.3V.
[2] The ADC is monotonic, there are no missing codes.
[3] The differential linearity error (E
D
) is the difference between the actual step width and the ideal step width. See Figure 5.
[4] The integral non-linearity (E
L(adj)
) is the peak difference between the center of the steps of the actual and the ideal transfer curve after
appropriate adjustment of gain and offset errors. See Figure 5
.
[5] The offset error (E
O
) is the absolute difference between the straight line which fits the actual curve and the straight line which fits the
ideal curve. See Figure 5
.
[6] The gain error (E
G
) 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. See Figure 5
.
[7] The absolute voltage error (E
T
) is the maximum difference between the center of the steps of the actual transfer curve of the
non-calibrated ADC and the ideal transfer curve. See Figure 5
.
