high-frequency components may be aliased into the
frequency band of interest. Minimize noise by present-
ing a low impedance (at the frequencies contained in
the noise signal) at the inputs. This requires bypassing
AIN to AGND, or buffering the input with an amplifier
that has a small-signal bandwidth of several MHz, or
preferably both. AIN has about 4MHz of bandwidth.
Distortion
Avoid degrading dynamic performance by choosing an
amplifier with distortion much less than the MAX1062
’
s
total harmonic distortion (THD = -99dB at 1kHz) at fre-
quencies of interest. If the chosen amplifier has insuffi-
cient common-mode rejection, which results in
degraded THD performance, use the inverting configu-
ration (positive input grounded) to eliminate errors from
this source. Low temperature-coefficient, gain-setting
resistors reduce linearity errors caused by resistance
changes due to self-heating. To reduce linearity errors
due to finite amplifier gain, use amplifier circuits with
sufficient loop gain at the frequencies of interest.
DC Accuracy
To improve DC accuracy, choose a buffer with an offset
much less than the MAX1062
’
s offset (1mV (max) for +5V
supply), or whose offset can be trimmed while maintain-
ing stability over the required temperature range.
Serial Interfaces
The MAX1062
’
s interface is fully compatible with SPI,
QSPI, and MICROWIRE standard serial interfaces.
If a serial interface is available, establish the CPU
’
s ser-
ial interface as master, so that the CPU generates the
serial clock for the MAX1062. Select a clock frequency
between 100kHz and 4.8MHz:
1) Use a general-purpose I/O line on the CPU to pull
CS
low.
2) Activate SCLK for a minimum of 24 clock cycles.
The serial data stream of eight leading zeros fol-
lowed by the MSB of the conversion result begins at
the falling edge of
CS
. DOUT transitions on SCLK

falling edge and the output is available in MSB-first
