DC579A

DC579A demonstration circuit features the LTC2600 octal 16-bit DAC. This device establishes a new board density benchmark for 16-bit DACs and advances performance standards for output drive, crosstalk and load regulation in single supply, voltage-output multiple DACs. The DC579A has many features for evaluating the performance of the LTC2600. Onboard 5V and 4.096V precision references are provided, and the- LTC2600 may be powered by the 5V reference for evaluating rail-to-rail operation. Another feature of this board is the onboard LTC2428 20- bit ADC for monitoring DAC output voltage. The 16ppm total error of this device is adequate for taking meaningful measurements of various LTC2600 parameters.

• 16-bits monotonicity at CC = 5V, VREF = 4.096V
• ±1LSB differential nonlinearity at VCC = 5V, VREF = 4.096V
• ±12LSB typical integral nonlinearity at VCC = 5V, VREF = 4.096V
• 3.5µV/mA DC crosstalk (due to load current change on any other channel)
• 2LSB/mA max load regulation (VCC = VREF = 5V, mid-scale IOUT = ±15 mA)
