Distortion
Avoid degrading dynamic performance by choosing an
amplifier with distortion much less than the total harmonic
distortion of the MAX1067/MAX1068 at the frequencies of
interest (THD = -98db at 1kHz). If the chosen amplifier
has insufficient common-mode rejection, which results in
degraded THD performance, use the inverting configura-
tion (positive input grounded) to eliminate errors from this
source. Low-temperature-coefficient, gain-setting resis-
tors reduce linearity errors caused by resistance
changes due to self-heating. To reduce linearity errors
due to finite amplifier gain, use amplifier circuits with suf-
ficient loop gain at the frequencies of interest..
DC Accuracy
To improve DC accuracy, choose a buffer with an offset
much less than the MAX1067/MAX1068s’ offset (±10mV
max for +5V supply), or whose offset can be trimmed
while maintaining stability over the required tempera-
ture range.
Serial Interfaces
SPI and MICROWIRE Interfaces
When using the SPI (Figure 20a) or MICROWIRE (Figure
20b) interfaces, set CPOL = 0 and CPHA = 0. Drive
CS
low to power on the MAX1067/MAX1068 before starting a
conversion (Figure 20c). Three consecutive 8-bit-wide
readings are necessary to obtain the entire 14-bit result
from the ADC. DOUT data transitions on the serial clock’s
falling edge. The first 8-bit-wide data stream contains all
leading zeros. The 2nd 8-bit-wide data stream contains
the MSB through D6. The 3rd 8-bit-wide data stream con-
tains D5 through D0 followed by S1 and S0.
