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’s
falling edge and the output is available in MSB-first
