neously. Three consecutive 8-bit readings (Figure 12b)
are necessary to obtain the entire 16-bit result from the
ADC. DOUT data transitions on the serial clock’s falling
edge and is clocked into the C 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 D8.
The third 8-bit data stream contains bits D7 through D0.
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 endpoints of the transfer func-
tion, once offset and gain errors have been nulled. The
static linearity parameters for the MAX1162 are mea-
sured 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 (tAJ) is the sample-to-sample variation in
the time between samples. Aperture delay (tAD) is the
time between the falling edge of the sampling clock
and the instant when the actual sample is taken.
