This is a DC570A user manual, which introduces how to evaluate LTC2440 with DC570A
The DC570A is a demonstration board designed for the LTC2440, a high-speed 24-bit delta-sigma ADC. It allows users to evaluate the ADC's performance by connecting it directly to target analog signals while using the DC590 USB Serial Controller board and supplied software. The board features exposed ground planes for proper grounding and includes jumpers to select reference sources and trigger modes.

The DC570A is a member of Linear Technology's QuikEval family of demonstration boards designed to allow easy evaluation of the LTC2440.
Connect the DC570A to the DC590 USB Serial Controller using the supplied 14-conductor ribbon cable.
Yes, by setting jumper JP1 to select the source for REF+ to external, and JP2 to select the source for REF– to external.
The exposed ground planes allow proper grounding to prototype circuitry.
