neously. Three consecutive 8-bit readings (Figure 12b)
are necessary to obtain the entire 14-bit result from the
ADC. DOUT data transitions on the serial clock
’
s falling
edge and is clocked into the μC on SCLK
’
s rising edge.
The first 8-bit data stream contains all zeros. The sec-
ond 8-bit data stream contains the MSB through D6.
The third 8-bit data stream contains bits D5 through D0
followed by S1 and S0.
Definitions
Integral Nonlinearity
Integral nonlinearity (INL) is the deviation of the values
on an actual transfer function from a straight line. This
straight line can be either a best-fit straight line fit or a
line drawn between the end points of the transfer func-
tion, once offset and gain errors have been nullified.
The static linearity parameters for the MAX1062 are
measured using the endpoint method.
Differential Nonlinearity
Differential nonlinearity (DNL) is the difference between
an actual step width and the ideal value of 1LSB. A
DNL error specification of 1LSB guarantees no missing
codes and a monotonic transfer function.
Aperture Definitions
Aperture jitter (t
AJ
) is the sample-to-sample variation in
the time between samples. Aperture delay (t
AD
) is the
14-Bit, +5V, 200ksps ADC with 10μA Shutdown
