ADDITIONAL INFORMATION
Although the DC1241 demo board is ready to use
on delivery, it has additional flexibility built in for
various types of input networks. Below is some
information about configuring DC1241 to meet the
specific needs of your evaluation.
APPLYING INPUT SIGNALS
The input network consists of various components
designed to allow either single-ended or differential
inputs, AC-coupled or DC-coupled. Table 2 shows
2
(see the section on Applying Input Signals). For
best results, use a low distortion, low noise sig-
nal generator with sufficient filtering to avoid de-
grading the performance of the amplifier and
ADC.
NOTE. Even a high-quality signal
synthesizer will still have noise
and harmonics that should be
attenuated with a low-pass or
band-pass filter. For good-quality
high order filters, see TTE, Lark
Engineering, or equivalent.

4. Observe the ADC output with demo circuit
some possible input configurations, and which
components to install. LTM9001 is designed for
excellent performance with both single-ended and
differential input drive, with little difference in distor-
tion performance. When using DC-coupled inputs,
the inputs to DC1241 need to be level-shifted to
within the input common-mode limits in the data-
sheet.
