Linear Technology DC1884A Series Demo Manual

DESCRIPTION
DC1884 supports the LTM
family.
The versions of the 1884A demo board are listed in Table 1.
Depending on the required resolution and sample rate,
the DC1884 is supplied with the appropriate ADC. The
circuitry on the analog inputs is optimized for analog input
