Linear Technology DC1732 Series Demo Manual

DESCRIPTION
Demonstration circuit DC1732 supports the LTM
high speed, quad ADC modules.
The versions of the 1732B demo board are listed in Table 1.
Depending on the required resolution and sample rate, the
DC1732 is supplied with the appropriate ADC. The circuitry
on the analog inputs is optimized for full bandwidth. Refer
