Description
Demonstration circuit 934A features the
16-bit DAC. This device establishes a new board-density
benchmark for 16-bit DACs and advances performance
standards for output drive, load regulation, and crosstalk
in single supply, voltage-output DACs.
DC934A has many features for evaluating the performance
of the LTC2607. Onboard 5V, 4.096V, and 2.5V precision
references are provided, and the LTC2607 may be powered
by the 5V reference for evaluating rail-to-rail operation.

Another feature of this board is the onboard LTC2422
20-bit ADC for monitoring DAC output voltage. The 16ppm
total error of this device is adequate for taking meaningful
measurements of various LTC2607 parameters.
