DC936A

DC936A demonstration circuit features the LTC®2609 quad 16bit DAC. This device establishes a new board-density benchmark for 16bit DACs and advances performance standards for output drive, crosstalk and load regulation in single supply, voltage-output multiple DACs. DC936A has many features for evaluating the performance of the LTC2609. Onboard 5V, 4.096V, and 2.5V precision references are provided. The LTC2609 features separate reference inputs for each DAC, and any of the onboard references can be used for any of the reference inputs. 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 LTC2609 parameters.

• 16bit monotonicity at VCC = 5V, VREF = 4.096V
• ±1LSB differential nonlinearity at VCC = 5V, VREF = 4.096V
• ±18LSB typical integral nonlinearity at VCC = 5V, VREF = 4.096V
• 2LSB/mA max load regulation at VCC = VREF = 5V, Mid-Scale IOUT = ±15mA
• 4µV/mA DC crosstalk (due to load current change on any other channel)
