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 prefer-
ably both. AIN has 4MHz (typ) of bandwidth.
Distortion
Avoid degrading dynamic performance by choosing an
amplifier with distortion much less than the MAX1162
’
s
total harmonic distortion (THD = -102dB 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 configuration (posi-
tive 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 MAX1162
’
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 MAX1162
’
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 MAX1162. 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
